The product is 74VHC373 Octal D-Type Latch with 3-STATE Outputs, which is an advanced high speed CMOS octal D-type latch with 3-STATE output fabricated with silicon gate CMOS technology. It achieves the high speed oper- ation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
The 74VHC373 is a high‑speed CMOS octal D‑type latch with three‑state outputs. It offers low power dissipation (loc = 4 µA max) and high noise immunity, and includes power‑down protection on all inputs. Latch enable (LE) controls data transparency, while output enable (OE) selects between normal and high‑impedance states.
The datasheet lists absolute maximum ratings, recommended operating conditions (2.0 V to 5.5 V supply), DC and AC electrical characteristics, propagation delays, and physical dimensions for SOIC, SOP, and TSSOP packages. Ordering information provides part numbers for each package option.
