74VHCT373A Octal D-Type Latch with 3-STATE Outputs July 1997 Revised April 1999 74VHCT373A Octal D-Type Latch with 3-STATE Outputs General Description The VHCT373A is an advanced high speed CMOS octal Dtype latch with 3-STATE output fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type latch is controlled by a latch enable input (LE) and an output enable i
