74ALVC164245
74ALVC164245 is 16-bit dual supply translating transceiver manufactured by NXP Semiconductors.
description
The 74ALVC164245 is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS patible TTL families.
The 74ALVC164245 is a 16-bit (dual octal) dual supply translating transceiver featuring non-inverting 3-state bus patible outputs in both send and receive directions. It is designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment.
This device can be used as two 8-bit transceivers or one 16-bit transceiver.
The direction control inputs (1DIR and 2DIR) determine the direction of the data flow. n DIR (active HIGH) enables data from n An ports to n Bn ports. n DIR (active LOW) enables data from n Bn ports to n An ports. The output enable inputs (1OE and 2OE), when HIGH, disable both n An and n Bn ports by placing them in a high-impedance OFF-state. Pins n An, n OE and n DIR are referenced to VCC(A) and pins n Bn are referenced to VCC(B).
In suspend mode, when one of the supply voltages is zero, there will be no current flow from the non-zero supply towards the zero supply. The n An-outputs must be set 3-state and the voltage on the A-bus must be smaller than Vdiode (typical 0.7 V). VCC(B) VCC(A) (except in suspend mode).
