Product Overview: CY54FCT373TDMB by Texas Instruments

The CY54FCT373TDMB is a high-performance CMOS Octal Transparent Latch manufactured by Texas Instruments, designed to provide efficient and reliable data storage in digital systems. This integrated circuit (IC) features eight latches that can hold the data presented on its inputs whenever the Latch Enable (LE) input is high, providing a transparent mode of operation. When LE is taken low, the latches store the information that was present at the inputs a setup time preceding the high-to-low transition of LE, effectively becoming opaque.

Constructed with advanced silicon-gate CMOS technology, the CY54FCT373TDMB offers the dual benefits of lower power consumption and increased speed, making it an excellent choice for interfacing with bus lines in a system. This device is particularly well-suited for applications that require high-speed and low power, such as computers, communication devices, and advanced microprocessor or microcontroller-based systems.

Key features of the CY54FCT373TDMB include:

• Logic Type: Octal Transparent Latch
• Logic Family: FCT
• Number of Bits per Element: 8
• Output Type: 3-State
• Package Type: 20-Pin Ceramic Dual-In-Line Package (CDIP)
• Operating Temperature Range: -55°C to +125°C, making it suitable for industrial and military applications.
• Supply Voltage Range: 4.5V to 5.5V
• Setup and Hold Times: Fast setup and hold times for high-speed operations.
• High Drive Outputs: -32mA IOH, 64mA IOL

The CY54FCT373TDMB also features a bus-hold data inputs function that eliminates the need for external pull-up or pull-down resistors, which simplifies board design and reduces board space requirements. The device's outputs, which are designed to sink and source significant current, provide a high degree of drive capability. The three-state outputs also allow for connection to bus lines or buffer memory address registers.

With its robust design and reliable performance, Texas Instruments' CY54FCT373TDMB is an ideal solution for temporary data storage and output buffering in your most demanding digital applications.
