74ABT16373

16-Bit Transparent D-Type Latch with 3-STATE Outputs

General Description

The ABT16373 contains sixteen non-inverting latches with

3-STATE outputs and is intended for bus oriented applica-

tions. The device is byte controlled. The flip-flops appear

transparent to the data when the Latch Enable (LE) is

HIGH. When LE is LOW, the data that meets the setup time

is latched. Data appears on the bus when the Output

Enable (OE) is LOW. When OE is HIGH, the outputs are in

high Z state.

Features

s Separate control logic for each byte

s 16-bit version of the ABT373

s High impedance glitch free bus loading during entire

power up and power down cycle

s Non-destructive hot insertion capability

s Guaranteed latch-up protection

Ordering Code:

Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
