XD40192 – CMOS Presettable BCD Up/Down Counter – Xinluda

The Xinluda XD40192 is a CMOS presettable 4-bit BCD (decade) up/down counter in a 16-pin DIP package, functionally equivalent to the industry-standard CD40192. Available for RFQ from Pacific Component Xchange.

The XD40192 from Xinluda is a CMOS presettable BCD (decade) up/down counter, part of the classic 4000-series logic family and functionally equivalent to the widely used CD40192. It integrates four synchronously clocked, gated “D”-type flip-flops configured as a 4-bit decade counter, with separate clock-up and clock-down inputs, a master reset, four parallel jam (preset) inputs, and a preset-enable control. Buffered carry and borrow outputs allow multiple counter stages to be cascaded without external gating, making the XD40192 a flexible building block for digital counting and frequency-division designs.

Supplied in a through-hole DIP-16 package, the XD40192 operates across a wide CMOS supply range, giving designers broad compatibility with 5V, 9V, 12V and 15V logic systems while maintaining the low quiescent power characteristic of the 4000-series CMOS process.

Key Features
