CD74AC373M96 is an 8-bit latch suitable for a wide variety of general-purpose register applications in digital systems where high speed operation and high noise immunity are required. This latch is designed for easy interface with any TTL logic families and provides temporary storage of data during output-enable signals. The latch offers eight noninverting buffered outputs which are ideal for driving bus lines directly.

The CD74AC373M96 is specified for operation with a 2.7V to 5.5V supply and is fully specified for operation from 0°C to 70°C. The latch has Schmitt-trigger inputs for provided requiring tight setup and hold times. The low power consumption and tiny package sizes offered by the CMOS technology reduce system power requirements.

Application Field

CD74AC373M96 latching technology is widely used in today’s systems requiring high speed and noise immunity. It offers a cost-effective solution which enables design engineers to integrate the logic, latching and output drive functions on one integrated circuit. These devices are particularly useful in applications where data bussing and multiplexing is necessary.

In communications systems, microcomputer based systems, instrumentation, peripheral equipment, and general-purpose computing devices, the latch is often employed. In addition, it can be used in systems with low-level data transmission and in systems with noise immunity requirements.

Working Principle

The CD74AC373M96 is an eight-bit latch that is triggered by an internal clock. When the clock is asserted, the input data is captured latched and retransmitted. The latch has eight noninverting buffered outputs that are ideal for driving bus lines directly. Clock pulse cycling with no delay is accomplished by repeated application of the Clock input. Data is held in the latches until the Clock input is again activated.

This series of latching devices consists of a pair of multiplexers and a pair of gate-level latches. The combination of the devices has no effect on the logic state of any of the outputs when the latch is in the latching or nonlatching state. When the Clock input is enabled, the logic level at the D input appears at the outputs of the eight latches. During the Clock disable state, the latches do not change states.

The CD74AC373M96 devices are designed for easy interface with any TTL logic families and can also be used in systems with a wide range of noise tolerances up to 10V. These devices are also useful in logic-level conversion due to their Schmitt-trigger inputs. The low-power consumption reduces system power requirements.
