HLF 74LS162 Presettable Synchronous BCD Decade Counter with Synchronous Reset – DIP16 | High-Speed TTL Logic | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

The HLF 74LS162 is a high-speed presettable synchronous BCD (Binary-Coded Decimal) decade counter built using Low-Power Schottky TTL technology. It features synchronous counting and reset functions, ensuring precise control of timing and sequencing operations. The counter advances through a binary-coded decimal sequence (0–9) and automatically resets to zero on the next clock pulse.

The parallel load feature allows the counter to be preset to any desired BCD value, while the synchronous reset ensures all outputs are cleared on the same clock edge, providing glitch-free operation. With fast switching speeds, low power dissipation, and reliable TTL performance, the DIP16 through-hole package makes it ideal for frequency dividers, digital clocks, control systems, and industrial logic circuits.
