Hot-selling and scarce 74LVCH8T245BQ,118 8-bit dual supply translating transceiver IC QFN spot stock

Product Features

The 74LVC8T245; 74LVCH8T245 are 8-bit dual supply translating transceivers with 3-state outputsthat enable bidirectional level translation . They feature two data input-output ports (pins An andBn), a direction control input (DIR), an output enable input (OE) and dual supply pins (V CC(A) andV CC(B)). Both V CC(A) and V CC(B) can be supplied at any voltage between 1.2 V and 5.5 V makingthe device suitable for translating between any of the low voltage nodes (1 .2 V, 1.5 V, 1.8 V, 2.5 V,3.3 V and 5.0 V). Pins An, OE and DIR are referenced to V CC(A) and pins Bn are referenced toV CC(B). A HIGH on DIR allows transmission from An to Bn and a LOW on DIR allows transmissionfrom Bn to An . The output enable input (OE) can be used to disable the outputs so the buses areeffectively isolated .

The devices are fully specified for partial power-down applications using I OFF . The _I OFF circuitrydisables the output, preventing any damaging backflow current through the device when it ispowered down . In suspend mode when either V CC(A) or V CC(B) are at GND level, both A port andB port are in the high-impedance OFF-state 

Active bus hold circuitry in the 74LVCH8T245 holds unused or floating data inputs at a valid logiclevel .
