3.3-V 10-BIT FLIP-FLOP WITH DUAL OUTPUTS
AND 3-STATE OUTPUTS
SCES035G – JULY 1995 – REVISED OCTOBER 2004
Member of the Texas Instruments Widebus
Family
Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
Latch-Up Performance Exceeds 250 mA Per
JESD 17
ESD Protection Exceeds JESD 22

This 10-bit flip-flop is designed for 1.65-V to 3.6-V
VCC operation.
The
flip-flops
of
the
SN74ALVCH16820
are
edge-triggered D-type flip-flops. On the positive
transition of the 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 logic level) or the 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
capability to drive bus lines without need for interface
or pullup components.
OE input 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.
To ensure the high-impedance state during power up
or power down, OE should be tied to VCC through a
pullup resistor; the minimum value of the resistor is
determined by the current-sinking capability of the
driver.
with the bus-hold circuitry is not recommended.
