IDT74ALVCHR162245 3.3V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74ALVCHR162245 BUS TRANSCIEVER WITH 3-STATE OUTPUTS AND BUS-HOLD DESCRIPTION: FEATURES: This 16-bit bus transceiver is built using advanced dual metal CMOS 0.5 MICRON CMOS Technology technology. The ALVCHR162245 device is designed for asynchronous Typical tSK(o) (Output Skew) < 250ps communication between data buses. The control-function implementation ESD > 2000V per MIL-STD-883, Method 3015 > 200V using minimizes external timing requirements. machine model (C = 200pF, R = 0) This device can be used as two 8-bit transceivers or one 16-bit VCC = 3.3V 0.3V, Normal Range transceiver. It allows data transmission from the A bus to the B bus or from VCC = 2.7V to 3.6V, Extended Range the B bus to the A bus, depending on the logic level at the direction control VCC = 2.5V 0.2V (DIR) input. The output-enable (OE) input can be used to disable the device CMOS power levels (0.4 W typ. static) so that the buses are effectively isolated. Rail-to-Rail output swing for increased noise margin The ALVCHR162245 has series resistors in the device output structure Available in TSSOP package which will significantly reduce line noise when used with light loads. This driver has been designed to drive 12mA at the designated threshold levels. DRIVE FEATURES: The ALVCHR162245 has bus-hold which retains the inputs last state Balanced Output Drivers: 12mA whenever the input bus goes to a high impedance. This prevents floating Low Switching Noise inputs and eliminates the need for pull-up/down resistors.
