74LS569A Datasheet (Motorola) - FOUR-BIT UP/DOWN COUNTER

74LS569A, FOUR-BIT UP/DOWN COUNTER

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).

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.
