Output ICs: Output ICs are available as either Line Driver (LD) or NPN Open Collector 1024 1200 1250 1440 (OC) types. Open Collectors require pull-up resistors, resulting in higher output source imped- ORN Z ance (sink impedance is similar to that of line drivers). In general, use of a Line Driver style 1800 2000 2048 2500 WHT/ORN Z output is recommended. Line Drivers source or sink current and their lower impedance mean 2540 better noise immunity and faster switching times. Warning: Do not connect any line driver BARE SHIELD DRAIN outputs directly to circuit common/OV, which may damage the driver. Unused outputs should be isolated and left floating. Our applications specialists would be pleased to discuss your Figure 1 Output Waveforms system requirements and the compatibility of your receiving electronics with Line Driver type outputs. 28V/V: Multi-voltage Line Driver (7272*): 100 mA source/sink. Input voltage 5 to 28 VDC +/- 5% standard (Note: V = V ). This driver is TTL compatible when used with 5 volt sup- out in ply. Supply lines are protected against overvoltage to 60 volts and reverse voltage. Outputs are short circuit protected for one minute. Supply current is 120 mA typical (plus load cur- rent). This is the recommended replacement for 3904R and 7406R open collector outputs with internal pullup resistors. It is also a direct replacement for any 4469, 88C30, 8830 or 26LS31 line driver. 28V/5: Multi-voltage Line Driver (7272*): 100 mA source/sink. Input voltage 5 to 28 VDC +/- 5% standard, internally regulated with 5V (TTL compatible) logic out. Supply lines are pro- tected against overvoltage to 60 volts and reverse voltage. Outputs are short circuit protected for one minute. Supply current is 90 mA typical (plus load current). Note: Limit encoder load to 2.5W max at ambient. Example at 12 VDC: 2.5W/(+12VDC minus +5VDC) = 357 mA total allowed current. Consult factory for your specific requirements. Dimensions 15V/V: Multi-voltage Line Driver (4469*): 100 mA source/sink. Input voltage 5 to 15 VDC +/- 5% standard (Note: V = V ). TTL compatible when used with 5 volt supply. Supply out in lines are protected against overvoltage to 60 volts and reverse voltage. Outputs are short circuit protected for one minute. Supply current is 90 mA typical (plus load current). This is a direct replacement for the 4469 Line Driver. 28V/OC: NPN Open Collector (3904*, 7273*). Current sink of 80 mA max. Current sourced by external pull- up resistor. Output can be pulled up to voltage other than supply voltage (30 + V max). Input voltage 5 to 28 VDC /- 5% standard. Supply current is 120 mA typical. This replaces prior ICs with designations of 3904, 7406, 3302, 681 and 689. 5V/OCR, 15V/OCR, 24V/OCR: Open Collector (3904R*, 7406R*, 7273R*): Current sink of 70 mA max. Includes internal pull-ups sized at approximately 100 ohms/volt. Max current source is 10 mA. Supply current is 100 mA typical, 120 mA with internal pull-ups. The 5V/ OCR, 15V/OCR and 24V/OCR are often replaced by the 28V/V in system upgrades. 6. Special S at the end of the model number is used to define a variety of non-standard features such as special shaft lengths, voltage options, or special testing. Please consult the factory to discuss your special requirements. 7. Higher frequency response may be available. Please consult with the factory. 8. Extended temperature ratings are available in the following ranges: -40 to 70C, -40 to 85C, 20 to 105C and 40 to 105C depending on the particular model. Some models can operate down to -55C. Extended temperature ranges can affect other performance fac- tors. Consult with factory for more specific information. * Products manufactured prior to April 2007 used the line driver IC number instead of voltage output in model number.
