74VCXH162374
Low Voltage 16-Bit D-Type Flip-Flop with Bushold
and 26Ω Series Resistors in Outputs
General Description
The VCXH162374 contains sixteen 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 16-bit opera-
tion.
The VCXH162374 data inputs include active bushold cir-
cuitry, eliminating the need for external pull-up resistors to
hold unused or floating data inputs at a valid logic level.
The 74VCXH162374 is also designed with 26Ω series
resistors in the outputs. This design reduces line noise in
applications such as memory address drivers, clock drivers
and bus transceivers/transmitters.
The 74VCXH162374 is designed for low voltage (1.65V to
3.6V) V
CC
applications with output compatibility up to 3.6V.
The 74VCXH162374 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
