The SN74LS193DR is a synchronous, 4-bit reversible (up/down) binary counter from Texas Instruments, built using LS technology. It offers a count rate of up to 32 MHz and operates within a voltage range of 4.75V to 5.25V. The counter features a positive edge trigger for its dual clock inputs, allowing for synchronous operation where all flip-flops change simultaneously. This eliminates counting spikes often seen in asynchronous counters.
Designed for flexibility, the SN74LS193DR is fully programmable. Each output can be preset to a desired level by using the data inputs while the load input is low. This capability allows the counter to function as a modulo-N divider. It includes an independent asynchronous clear input that forces all outputs to a low level. The device is designed for cascading without external circuitry, and it provides both borrow and carry outputs.
Packaged in a 16-SOIC format, the SN74LS193DR is suitable for surface mounting. Its operating temperature range is from 0°C to 70°C. The clear, count, and load inputs are buffered to reduce drive requirements, making it easier to integrate into larger systems. This counter is a reliable component for digital logic applications requiring precise counting and control.
