74ACT16373 16-Bit Transparent Latch with 3-STATE Outputs

August 1999 Revised May 2005

74ACT16373 16-Bit Transparent Latch with 3-STATE Outputs
General Description
The ACT16373 contains sixteen non-inverting latches with 3-STATE outputs and is intended for bus oriented applications. 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 ACT373 s Outputs source/sink 24 mA s TTL-compatible inputs
