74VHCT374A

The 74VHCT374A is an advanced high-speed CMOS OCTAL D-TYPE FLIP FLOP with 3 STATE OUTPUTS NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C²MOS technology.

These 8 bit D-type flip-flop of the 74VHCT374A is controlled by a clock input (CK) and an output enable input (OE).

On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs.

When the (OE) input is low, the 8 outputs will be in a normal logic state (high or low logic level) and when (OE) is in high level, the outputs will be in a high impedance state.

The Output control does not affect the internal operation of flip flops; that is, the old data can be retained or the new data can be entered even while the outputs are off.

Power down protection of the 74VHCT374A is provided on all inputs and outputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V since all inputs are equipped with TTL threshold.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
