XD74LS192 – Logic Counter IC – Xinluda

The XD74LS192 from Xinluda is a presettable BCD (decade) synchronous up/down counter in a DIP-16 package, part of the classic 74LS TTL logic family. Available for RFQ through Pacific Component Xchange.

The XD74LS192 is Xinluda’s implementation of the industry-standard 74LS192 presettable BCD/decade (8421) synchronous reversible counter. As a 4-bit counter built on bipolar Low-power Schottky (LS) TTL technology, it counts both up and down through ten states using separate Count Up and Count Down clock inputs, with all flip-flops clocked simultaneously for synchronous operation that eliminates the output spikes associated with ripple counters. The device is supplied in a through-hole DIP-16 package, making it well suited for legacy designs, repair, and education boards.

Key Features

• Presettable BCD/decade (8421) synchronous up/down counter
• 4-bit, monolithic synchronous reversible counter architecture
• Separate Count Up and Count Down clock inputs determine count direction
• Individual parallel preset (data) inputs for programmable counting
• Terminal Count Up and Terminal Count Down outputs for cascading multistage counters without external logic
• Asynchronous Parallel Load (PL) and Master Reset (Clear) that override the clocks
• Low-power Schottky (LS) TTL family, nominal 5 V supply operation
• Operating ambient temperature range: 0 C to +70 C
• 16-pin DIP (DIP-16) through-hole package

Applications

• Decimal (BCD) counting and frequency division
• Programmable / presettable counters and timers
• Multistage cascaded counter chains
• Industrial control and instrumentation logic
• Legacy equipment repair and board-level replacement
• Education and prototyping / hobbyist logic projects
