Product Overview: Texas Instruments CD54HCT573F

The Texas Instruments CD54HCT573F is a high-performance, octal transparent D-type latch that is part of the HCT (High-Speed CMOS Logic) family. Designed to operate at a voltage range of 4.5V to 5.5V, this integrated circuit provides the functionality of eight latches in a single package, making it a compact and efficient solution for a wide range of digital applications.

This device features eight D-type latches with 3-state outputs. Each latch is capable of storing a single bit of data when the latch enable (LE) input is high. The data on the D inputs is transferred to the latch outputs on the falling edge of the LE signal. The 3-state outputs (Q) can be set to either a high, low, or high-impedance state, which adds flexibility in bus-oriented applications by allowing multiple outputs to be connected to a common bus without the risk of bus contention.

The CD54HCT573F is characterized for operation over the full military temperature range of -55°C to 125°C. Its robust design ensures reliable performance in demanding environments, making it suitable for use in military, aerospace, and other high-reliability applications. The device comes in a hermetically sealed ceramic dual-inline package (CERDIP), which provides excellent protection against harsh conditions and ensures the longevity of the device.

Key features of the CD54HCT573F include:

• Eight D-type latches in a single package for increased density
• 3-state outputs for bus interfacing
• Wide operating voltage range of 4.5V to 5.5V
• Compatible with LS output drive
• Low power consumption
• High noise immunity characteristic of CMOS devices
• Hermetically sealed package for high-reliability applications
• Full military temperature range operation

Whether you are designing a complex digital system or need reliable latching capabilities for your circuit, the Texas Instruments CD54HCT573F offers a trusted solution. Its combination of high-speed performance, durability, and 3-state output control makes it a versatile choice for your digital logic needs.
