74LVCH32374AEC,551

1. General description
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 device 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 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.
Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused
inputs.
2. Features and benefits
