OCTAL EDGE-TRIGGERED D-TYPE FLIP-FLOPS
WITH 3-STATE OUTPUTS
SCLS148F − DECEMBER 1982 − REVISED AUGUST 2003
Wide Operating Voltage Range of 2 V to 6 V High-Current 3-State Noninverting Outputs
Drive Bus Lines Directly or Up To 15 LSTTL
Loads Low Power Consumption, 80-μA Max ICC Typical tpd = 22 ns ±6-mA Output Drive at 5 V
Low Input Current of 1 μA Max Bus-Structured Pinout
description/ordering informationThese octal edge-triggered D-type flip-flops
feature 3-state outputs designed specifically for
bus driving. They are particularly suitable for
implementing buffer registers, I/O ports,
bidirectional bus drivers, and working registers.
The eight flip-flops enter data on the low-to-high
transition of the clock (CLK) input.
A buffered output-enable (OE) input can be used
to place the eight outputs in either a normal logic
state (high or low logic levels) 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 interface or pullup components.
