74LS569 Counter SYNCH 4-Bit U/D 5V IC DIP-20

From the shop's description

74LS569 Counter SYNCH 4-Bit U/D 5V IC DIP-20 The 74LS569 belongs to the 74LS family of TTL logic devices and is intended for digital counting applications that require a 4-bit binary count sequence. A synchronous counter updates its internal state in response to the active clock transition, allowing coordinated counting across its output bits. The up/down counting function allows the count to increase or decrease according to the control input. This makes the device useful in event counters, digital control systems, position-counting circuits, and other logic designs that need reversible counting. The specified DIP-20 package supports through-hole mounting and circuit prototyping. Features: Synchronous 4-bit binary counting. Supports both up-counting and down-counting. Parallel data loading. Clock-controlled counting operation. Clear and reset control functions. Count enable inputs for controlling counter operation. Carry outputs for cascading multiple counters. Three-state outputs for bus interfacing. TTL-compatible logic. Suitable for digital counting and control circuits.
