描述 Description

The AiP74ALVC164245 is a high-performance, low-power, low-voltage, Si-gate CMOS device,superior to most advanced CMOS compatible TTL families.The AiP74ALVC164245 is a 16-bit (dual octal) dual supply translating transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. It is designed to interface between a 3V and 5V bus in a mixed 3V and 5V 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.nDIR (active HIGH) enables data from nAn ports to nBn ports. nDIR (active LOW) enables data from nBn ports to nAn ports. The output enable inputs (1 and 2 ), when HIGH, disable both nAn and nBn ports by placing them in a high-impedance OFF-state. Pins nAn, n and nDIR are referenced to VCC(A) and pins nBn 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 nAn-outputs must be set 3-state and the voltage on the A-bus must be smaller than Vdiode (typical 0.7V). VCC(B)≥VCC(A) (except in suspend mode).
