74LS162 DIP-16 Synchronous 4-Bit Decade Counter IC (TTL, 5V)

Description -

The 74LS162 DIP is a TTL logic integrated circuit that functions as a synchronous presettable 4-bit decade (BCD) counter in a 16-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed for high-speed counting, frequency division, timing, and digital control applications.

The IC counts in a Binary Coded Decimal (BCD) sequence from 0 to 9 and features a synchronous clear input, ensuring reset operations occur only on the next rising edge of the clock for glitch-free performance. It also includes parallel load inputs, dual count enable inputs, and a ripple carry output, making it ideal for cascading multiple counters in synchronous digital systems.
