CD74AC373E Octal Transparent D-Type Latches from Texas Instruments

The CD74AC373E is a high-speed octal transparent D-type latch designed and manufactured by Texas Instruments, a leader in the semiconductor industry. This integrated circuit is part of the AC series, known for its advanced high-speed CMOS technology, and is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working memory.

Featuring a robust latch function, the CD74AC373E allows inputs to be transferred to outputs when the latch-enable (LE) input is high. The data is held stable when the LE is taken low. This device also includes an octal D-type flip-flop with three-state outputs, which can be used to interface with bus lines in a bus-organized system. When the output-enable (OE) is high, the outputs are in a high-impedance state, ensuring that there is no conflict with other components connected to the bus.

Key specifications of the CD74AC373E include:

• Operating Voltage Range: 2V to 6V
• Maximum Operating Frequency: 190 MHz at 5V
• Low Power Consumption: ICC reduced by 50%
• 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
• Outputs Source/Sink 24 mA

Designed for use in a wide range of applications, the CD74AC373E is ideal for computer and computer-peripheral applications, where its high-speed operation and low power consumption are highly beneficial. The device is also widely used in data storage, data acquisition, and communication systems.

The package for the CD74AC373E is a standard PDIP-20 (Plastic Dual-In-Line Package), which is easy to handle and integrate into a variety of electronic assemblies. Texas Instruments ensures that this product meets rigorous quality and performance standards, making it a reliable choice for designers and engineers looking to build high-performance electronic systems.
