Diodes Incorporated PT74HC373PE - Octal Transparent D-Type Latch

The PT74HC373PE is a high-speed CMOS Octal Transparent D-Type Latch designed and manufactured by Diodes Incorporated, a leading global manufacturer and supplier of high-quality application-specific standard products within the broad discrete, logic, and analog semiconductor markets. This integrated circuit is part of the HC family and is compatible with Low Power Schottky TTL (LSTTL).

Featuring eight latches with three-state outputs for bus organized systems applications, the PT74HC373PE is optimized for use in a wide array of electronic equipment including computers, data storage, communication systems, and other applications that require high-speed data control and storage.

Key Features:

• Logic Type: Octal D-Type Latch with 3-state outputs
• Number of Pins: 20-pin DIP package for easy integration into circuit boards
• High-Speed Operation: Ensures quick response times suitable for high-performance systems
• Wide Operating Voltage Range: 2V to 6V, providing compatibility with a variety of logic levels and systems
• Low Power Consumption: Ideal for power-sensitive applications
• Output Drive Capability: Capable of driving 15 LSTTL loads, ensuring reliable performance in complex circuits

The PT74HC373PE latches are transparent D-type latches, meaning that while the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. An additional feature of this device is the common output enable (OE) input that controls all eight 3-state outputs and is used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly, allowing for multiple devices to be connected to the bus line for a multiplexed data transmission.

The PT74HC373PE is fabricated with silicon gate CMOS technology, which provides the inherent benefits of CMOS—low quiescent power and high noise immunity. The robust design of the PT74HC373PE allows for stable and reliable performance in demanding applications, making it a preferred choice for design engineers.

Overall, the PT74HC373PE from Diodes Incorporated is a versatile and reliable component that offers high-speed operation and low power consumption, making it an excellent choice for a broad range of electronic systems.
