This device be usedas two 8-bit transceiversor 16-bit transceiver.It allows data transmission from the
SN74LVCR162245
16-BIT BUS TRANSCEIVER Memberof the Texas Instruments Widebus™ All Outputs Have Equivalent 26-Ω Series
Resistors, So No External Resistors Are
Required Latch-Up Performance Exceeds 250 mA Per
JEDEC JESD-17 ESD Protection Exceeds JESD22 2000-V Human-Body Model (A114-A) 200-V Model (A115-A)This 16-bit noninverting bus transceiveris
designed 2.7-Vto 3.6-VVCC operation.
The SN74LVCR162245is designed for asynchronous
communication between data buses. The
control-function implementation minimizes external
timing requirements. busto theB busor from theB busto theA bus, depending upon the logic levelat the direction-control (DIR)
input. The (OE) input canbe usedto disable the deviceso that the buses effectively are isolated.
All outputs, are designedto sinkupto12 mA, include 26-Ω resistorsto reduce overshoot and undershoot.
Active bus-hold circuitryis providedto hold unusedor data inputsata valid logic level. Useof pullupor
pulldown with the bus-hold circuitryis not The bus-hold circuitryis partof the input
circuit and not disabledby OEor DIR.
