The 74LVCH32374A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families.
The inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, the outputs can handle 5 V. These features allow the use of these devices in a mixed 3.3 V or 5 V environment.
The 74LVCH32374A is a 32-bit edge-triggered flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus oriented applications. The 74LVCH32374A consists of 4 sections of 8 edge-triggered flip-flops. A clock (pin nCP) input and an output enable input (pin nOE) are provided per 8-bit section.
The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH nCP transition.
When pin nOE is LOW, the contents of the flip-flops are available at the outputs. When pin nOE is HIGH, the outputs go to the high-impedance OFF-state. Operation of pin nOE does not affect the state of the flip-flops.
The 74LVCH32374A bushold data input circuits eliminate the need for external pull-up resistors to hold unused inputs.
