Product Overview: CD54HCT373F3A from Texas Instruments

The CD54HCT373F3A is a high-performance, CMOS logic-level octal transparent D-type latch designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This integrated circuit is part of the HCT family, which means it is compatible with TTL (Transistor-Transistor Logic) levels, allowing for easy integration into a wide range of digital systems that require TTL compatibility.

The CD54HCT373F3A features eight latches with 3-state outputs in a single package, providing a convenient means to interface 8-bit data from a bus-oriented system. Each latch is transparent; that is, data on the input will appear at the output when the latch enable (LE) is high, and will be retained when LE is low. The 3-state outputs ensure that the latches can be connected directly to a bus, and can be either driven high, driven low, or placed in a high-impedance state, thereby preventing bus contention.

Key Specifications:

• Logic Type: Octal D-Type Transparent Latch
• Output Type: 3-State
