HLF 74LS163 Presettable Synchronous 4-Bit Binary Counter with Synchronous Reset – DIP16 | High-Speed TTL Logic | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

The HLF 74LS163 is a high-speed presettable synchronous 4-bit binary counter designed using Low-Power Schottky TTL (LS) technology. It provides synchronous counting and resetting, ensuring all outputs change simultaneously with the clock pulse for accurate and glitch-free operation.

The device includes parallel load capability, allowing presetting to any binary value, and supports count enable and carry output functions for cascading multiple counters. Operating from 4.75V to 5.25V within a temperature range of 0°C to +70°C, the 74LS163 DIP16 package offers fast switching speed, low power dissipation, and excellent noise immunity — making it ideal for timing, sequencing, and control logic circuits.
