Product Description
Pericom Semiconductor’s PI74ALVCH series of logic circuits are
produced in the Company’s advanced 0.5 micron CMOS technology,
achieving industry leading speed.
The PI74ALVCH162820 is a 10-bit flip-flop designed for 2.3V to 3.3V
V
CC
operation. The PI74ALVCH162820 is designed with edge-
triggered D-type flip-flops. On the positive transition of clock (CLK)
input, the device provides true data at the Q outputs.
A buffered output-enable (OE) input can be used to place the ten
outputs in either a normal logic state (HIGH or LOW level) or a high-
impedance state. In the high-impedance state, the outputs neither
load nor drive the bus lines significantly. The high-impedance state
and increased drive provide the capacity to drive bus lines without
the need for interface or pullup components. OE does not affect the
internal operation of the flip-flops. Old data can be retained or new
data can be entered while the outputs are in the high-impedance
state.
The outputs, which are designed to sink up to 12mA, include
26
resistors to reduce overshoot and undershoot.
The PI74ALVCH162820 has “Bus Hold” which retains the data
input’s last state whenever the data input goes to high-impedance
preventing “floating” inputs and eliminating the need for pullup/
down resistors.
Active bus-hold circuitry is provided to hold unused or floating
data inputs at a valid logic level.
