54ABT16245
16-Bit Transceiver with TRI-STATE® Outputs
General Description
The ’ABT16245 contains sixteen non-inverting bidirectional
buffers with TRI-STATE outputs and is intended for bus ori-
ented applications. The device is byte controlled. Each byte
has separate control inputs which can be shorted together
for full 16-bit operation. The T/R inputs determine the direc-
tion of data flow through the device. The OE inputs disable
both the A and B ports by placing them in a high impedance
state.
n Separate control logic for each byte
n 16-bit version of the ’ABT245
n A and B output sink capability of 48 mA, source
capability of 24 mA
n Guaranteed latchup protection
n High impedance glitch free bus loading during entire
power up and power down cycle
n Non-destructive hot insertion capability
n Standard Microcircuit Drawing (SMD) 5962-9317501
Features
n Bidirectional non-inverting buffers
