74LVT32374 74LVTH32374
Low Voltage 32-Bit D-Type Flip-Flop
with 3-STATE Outputs
General Description
The LVT32374 and LVTH32374 contain thirty-two non-
inverting D-type flip-flops with 3-STATE outputs and are
intended for bus oriented applications. The device is byte
controlled. A buffered clock (CP) and Output Enable (OE)
are common to each byte and can be shorted together for
full 32-bit operation.
The LVTH32374 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These flip-flops are designed for low-voltage (3.3V) V
CC
applications, but with the capability to provide a TTL inter-
face to a 5V environment. The LVT32374 and LVTH32374
are fabricated with an advanced BiCMOS technology to
achieve high speed operation similar to 5V ABT while
maintaining a low power dissipation.
