The SN74ACT373PWR from Texas Instruments is a high-performance, octal transparent D-type latch with a wide operating voltage range and the ability to drive up to 15 LSTTL loads. This integrated circuit is designed to be used in storage and data transfer systems where high speed and reliability are paramount.

Key Features:

• Logic Type: Octal Transparent D-Type Latches with 3-State Outputs
• Package / Case: TSSOP-20
• Operating Temperature: -40°C to +85°C, making it suitable for industrial applications
• Logic Family: ACT
• Logic Voltage: 4.5V to 5.5V
• IC Output Type: Tri-State
• Propagation Delay Time: Typically 6.5ns at 5V, 50pF
• Current - Output High, Low: 24mA, 24mA

Product Description:

The SN74ACT373PWR is designed to provide storage for 8-bit data with its octal D-type latches. The transparent nature of the latches means that while the latch-enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.

An important feature of the SN74ACT373PWR is its 3-state outputs, which can be placed in a high-impedance state. This is particularly useful in bus-oriented systems where multiple outputs can share the same connection lines without interference.

The device's high-speed and robust construction, with its ability to drive 15 LSTTL loads, make it an excellent choice for interfacing with high-speed microprocessors. The SN74ACT373PWR is also characterized for operation from -40°C to +85°C, which ensures reliable performance in a wide range of environmental conditions.

Whether it's used in buffer memory address registers, working registers, or as a part of a control system, the SN74ACT373PWR provides a combination of high-speed and high-density that is hard to match. This product is available in a TSSOP-20 package, which is optimized for reduced space in printed circuit board layouts.

Applications:

• Buffer Memory Address Registers
• Control Systems
• Data Storage and Transfer
• Working Registers in Microprocessor Systems
