74VCX32374
Low Voltage 32-Bit D-Type Flip-Flops
with 3.6V Tolerant Inputs and Outputs
General Description
The VCX32374 contains thirty-two non-inverting D-type
flip-flops with 3-STATE outputs and is intended for bus ori-
ented applications. The device is byte controlled. A buff-
ered clock (CP) and output enable (OE) are common to
each byte and can be shorted together for full 32-bit opera-
tion.
The 74VCX32374 is designed for low voltage (1.2V to
3.6V) V
CC
applications with I/O compatibility up to 3.6V.
The 74VCX32374 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
