HLF 74LS161 Presettable Synchronous 4-Bit Binary Counter with Asynchronous Reset – DIP16 | High-Speed TTL Logic | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

The HLF 74LS161 is a Low-Power Schottky TTL 4-bit synchronous binary counter with asynchronous reset and presettable parallel load inputs, designed for high-speed counting, timing, and control applications. The counter operates synchronously with the clock signal for reliable, predictable counting and can be preset to any binary value.

With fast propagation times, low power consumption, and excellent noise immunity, the DIP16 through-hole package offers robust TTL-level performance in industrial, automation, and embedded systems.
