SN54/74LS569A

FOUR-BIT UP/DOWN COUNTER

WITH THREE-STATE OUTPUTS

The SN54/74LS569A is designed as programmable up/down BCD and

Binary counters respectively. These devices have 3-state outputs for use in

bus organized systems. With the exception of output enable (OE) and

asynchronous clear (ACLR), all functions occur on the positive edge of the

clock pulse (CP).

FOUR-BIT UP/DOWN COUNTER

WITH THREE-STATE OUTPUTS

LOW POWER SCHOTTKY

When the LOAD input is LOW, the outputs will be programmed by the

parallel data inputs (A, B, C, D) on the next clock edge. Enabling of the

counters occurs only when CEP and CET are LOW and LOAD is HIGH.

Direction of the count is controlled by the up-down input (U/D), HIGH counts

up and LOW counts down. High-speed counting and cascading is implement-

ed by internal look-ahead carry logic and an active LOW ripple carry output

(RCO). On the LS569A, the RCO is LOW at binary 15 during up-count and

during down-count it is also LOW at binary 0. During normal cascading

operation RCO connected to the succeeding block at CET is the only

requisite. When counting and when RCO is LOW, the clocked carry output

(CCO) provides a HIGH-LOW-HIGH pulse for a duration equal to the LOW

time of the clock pulse. Two active LOW reset lines are provided, a master

reset asynchronous clear (ACLR) and a synchronous clear (SCLR). When in

a HIGH state, the output control (OE) input forces the counter output into a

HIGH impedance state and when LOW, the counter outputs are enabled.
