SN74AHCT373DB Octal Transparent D-Type Latches

The SN74AHCT373DB from Texas Instruments is a high-performance, octal transparent D-type latch with 3-state outputs designed for 4.5-V to 5.5-V VCC operation. This integrated circuit is part of the 'AHCT' family of products, which are known for their ability to interface between 5V and CMOS logic levels while maintaining speed and consuming low power.

This device features eight latches with 3-state outputs for bus-oriented applications. The latches appear transparent to data when the Latch Enable (LE) input is high. When LE is taken low, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is low. When OE is high, the outputs are in a high-impedance state, which means they neither load the bus nor drive it, allowing for bus line control in a shared-line environment.

The SN74AHCT373DB is characterized for operation from -40°C to 85°C, making it a suitable choice for industrial temperature ranges. This device comes in a 20-pin SSOP (DB) package, which is ideal for space-conscious applications. The pin configuration and functional compatibility with other standard logic families make the SN74AHCT373DB a versatile component for a wide range of digital logic applications.

Key features of the SN74AHCT373DB include:

• Eight D-type latches in a single package
• 3-state outputs for bus interfacing
• Compatible with 5V TTL logic levels
• Low power consumption
• Edge-triggered from high-to-low transitions on LE
• Wide operating voltage range of 4.5V to 5.5V
• Industrial operating temperature range of -40°C to 85°C
• Compact 20-pin SSOP packaging for space-saving applications

Whether for use in microprocessor or microcomputer systems, memory buffers, or as part of a larger digital system requiring a high degree of data control, the SN74AHCT373DB offers a reliable and efficient solution for data latching needs.
