Motorola => Freescale
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).
• ESD > 3500 Volts
