74ALVC162374
Low Voltage 16-Bit D-Type Flip-Flop
with 3.6V Tolerant Inputs and Outputs
and 26Ω Series Resistors in Outputs
General Description
The ALVC162374 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 ALVC162374 is also designed with 26Ω series resis-
tors in the outputs. This design reduces line noise in appli-
cations such as memory address drivers, clock drivers and
bus transceivers/transmitters.
The 74ALVC162374 is designed for low voltage (1.65V to
3.6V) VCC applications with I/O compatibility up to 3.6V.
The 74ALVC162374 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
Features
s 1.65V–3.6V VCC supply operation
s 3.6V tolerant inputs and outputs
s 26Ω series resistors in outputs
s tPD (CLK to On)
3.9 ns max for 3.0V to 3.6V VCC
5.3 ns max for 2.3V to 2.7V VCC
9.6 ns max for 1.65V to 1.95V VCC
s Power-off high impedance inputs and outputs
s Supports live insertion and withdrawal (Note 1)
s Uses patented noise/EMI reduction circuitry
s Latchup conforms to JEDEC JED78
s ESD performance:
Human body model > 2000V
Machine model > 200V
Note 1: To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
