Working principle CD74AC374M96E4

The CD74AC374M96E4 is a high-speed CMOS octal transparent latch and edge-triggered flip flop, consisting of four flip-flops that are configured to provide 8-bit data capture, 8-bit buffering and two additional latches. It has an input data capture rate of over 80 MHz and is built with a low current level-sensitive input architecture to provide low power operation.

One of the key features of the CD74AC374M96E4 is its level-sensitive input feature, which allows the device to capture and store data on both the rising and falling edges of the input clock signal. The device operates in both asynchronous (level-triggered) and synchronous (edge-triggered) mode. In asynchronous mode, data is transferred from the data input to the D-type latch on the rising edge of the clock signal (DFFenable) while in synchronous mode data is transferred on the rising and fallingedge of the clock signal.

The device has two modes, set/reset and push-pulse/toggle. In set/reset mode, the device operates as a conventional latch with the set (S) and reset (R) inputs controlling the state of the output. In push-pulse/toggle mode, the device operates as a toggle flip-flop to latch data on the rising edge of the data enable (DFFen). In this mode, a high input level applied to the data enable input forces the device to toggle from the current state.

The CD74AC374M96E4 also has an asynchronous active low reset feature that sets all outputs to the low state when enabled. The reset is inhibited when DFFen is low. This feature allows the device to maintain a valid state for both normal and abnormal operation conditions.

The CD74AC374M96E4 is designed to operate from 0°C to 70°C and with a wide range of power supply voltages. All outputs are designed for TTL logic levels, providing an excellent solution for systems that require high speed data transfer and buffering capability, with low quiescent current.
