74LS373 Octal D-Type Transparent Latch IC

The 74LS373 is a low-power, high-speed Octal D-type Flip-Flop with independent D-type inputs for each flip-flop and three-state outputs for bus-oriented applications. All flip-flops in the IC receive a buffered Clock (CP) and Output Enable (OE). The flip-flops look transparent to the data when Latch Enable (LE) is HIGH (data changes asynchronously). When LE is set to LOW, the data that matches the setup times locks. When the Output Enable (OE) is LOW, the Data also displays on the bus. The bus output is in a high impedance state when OE is HIGH.

A D-type latch/flip-flop with two stable states that is designed as a timed latch. A D-type latch has a one-clock-cycle delay in its input. Delay circuits are frequently produced by cascading multiple D-type flip-flops. This was then used in a variety of applications, such as digital television systems. A D flip-flop, sometimes known as a delay flip-flop, is a D-type flip-flop.

Applications

• Used for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers in modern computing systems
