74LVCH32245A 3.3V CMOS 32-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 32-BIT 74LVCH32245A BUS TRANSCEIVER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O, BUS-HOLD FEATURES: DESCRIPTION: Typical tSK(o) (Output Skew) < 250ps This 32-bit bus transceiver is built using advanced dual metal CMOS ESD > 2000V per MIL-STD-883, Method 3015 > 200V using technology. This high-speed, low power transceiver is ideal for asynchro- machine model (C = 200pF, R = 0) nous communication between two busses (A and B). The Direction and VCC = 3.3V 0.3V, Normal Range Output Enable controls are designed to operate the device as either four VCC = 2.7V to 3.6V, Extended Range independent 8-bit transceivers or one 32-bit transceiver. The direction CMOS power levels (0.4 W typ. static) control pins (DIR) control the direction of data flow. The output enable pins All inputs, outputs, and I/O are 5V tolerant (OE) override the direction control and disable both ports. All inputs are Supports hot insertion designed with hysteresis for improved noise margin. Available in 96-ball LFBGA package All pins can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V supply system. The LVCH32245A has been designed with a 24mA output driver. This DRIVE FEATURES: driver is capable of driving a moderate to heavy load while maintaining Balanced Output Drivers: 24mA speed performance Reduced system switching noise The LVCH32245A has bus-hold which retains the inputs last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors. APPLICATIONS: 5V and 3.3V mixed voltage systems Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM A3 J3 1DIR 3DIR A4 J4 1OE 3OE A5 J5 1A1 3A1 A2 J2 1B1 3B1 TO SEVEN OTHER CHANNNELS TO SEVEN OTHER CHANNNELS H3 T3 2DIR 4DIR T4 H4 2OE 4OE E5 N5 2A1 4A1 N2 E2 2B1 4B1 TO SEVEN OTHER CHANNNELS TO SEVEN OTHER CHANNNELS INDUSTRIAL TEMPERATURE RANGE 1 Apr.01.2174LVCH32245A 3.3V CMOS 32-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE PIN CONFIGURATION 3A6 6 1A2 1A4 1A6 1A8 2A2 2A4 2A6 2A7 3A2 3A4 3A8 4A2 4A4 4A6 4A7 5 2A1 2A3 1A1 1A3 1A5 1A7 2A5 2A8 3A1 3A3 3A5 3A7 4A1 4A3 4A5 4A8 4 2OE GND VCC VCC GND 3OE 1OE GND GND GND VCC GND GND VCC GND 4OE 4DIR 3 GND VCC VCC GND 2DIR GND 1DIR GND GND 3DIR GND VCC GND VCC GND 2 1B1 1B3 1B7 2B8 3B3 3B5 4B1 4B3 4B8 1B5 2B1 2B3 2B5 3B1 3B7 4B5 1 1B2 1B4 1B6 1B8 2B2 3B2 3B4 3B6 3B8 4B4 4B6 4B7 2B4 2B6 2B7 4B2 A B C D E F G H J K L M N P R T LFBGA TOPVIEW 2 Apr.01.21
