Low Voltage 16-Bit D-Type Flip-Flop with Bushold
and 26Ω Series Resistors in Outputs
The ALVCH162374 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-
The ALVCH162374 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 74ALVCH162374 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 74ALVCH162374 is designed for low voltage
(1.65V to 3.6V) VCC applications with output compatibility
up to 3.6V.
The 74ALVCH162374 is fabricated with an advanced
CMOS technology to achieve high speed operation while
maintaining low CMOS power dissipation.
