Product Description
The SN74ACT373PW is equipped with eight D-type latches that feature 3-state outputs designed to drive bus lines or buffer memory address registers. The device comes in a 20-pin TSSOP package, which is ideal for surface-mounted applications and space-constrained environments.
Each latch has a D-type input and an output enable (OE) pin. When OE is low, the data on the D inputs are transferred to the latch outputs. When OE is high, the outputs are in a high impedance state, which means they neither load nor drive the bus line significantly.
With a wide operating voltage range of 4.5 V to 5.5 V, this latch can be used in various logic systems and is fully compatible with 5 V TTL logic. The SN74ACT373PW also boasts a robust design that ensures reliable operation over a temperature range of -40°C to 85°C, making it suitable for industrial applications.
Overall, the SN74ACT373PW from Texas Instruments is a reliable choice for designers who require a high-speed, low-power octal latch with the added flexibility of 3-state outputs.
