Frequently Asked Questions
What is the SN74HC193D and what does it do?
The SN74HC193D is a high-speed CMOS 4-bit synchronous binary up/down counter from Texas Instruments. It features separate clock inputs for up and down counting, asynchronous parallel load, and an asynchronous master reset. It operates from a 2V to 6V supply and is housed in a 16-pin SOIC package.
What are the key specifications of the SN74HC193D?
Key specifications include a 4-bit binary counting range (0–15), independent UP and DOWN clock inputs, asynchronous active-low LOAD and CLR pins, carry output (RCO) and borrow output (RBO) for cascading, TTL-compatible I/O levels, and a wide supply voltage range of 2V to 6V. Typical propagation delay is around 13 ns at 5V.
How do I cascade multiple SN74HC193D devices for wider counting?
To cascade SN74HC193D devices for wider bit-width counting, connect the carry output (RCO) of the lower-order stage to the UP clock of the next stage, and the borrow output (RBO) to the DOWN clock of the next stage. This allows straightforward 8-bit, 12-bit, or wider synchronous counter implementations without additional logic.
What applications is the SN74HC193D suited for?
The SN74HC193D is suited for frequency division, event counting, programmable timers, address sequencing in embedded systems, and industrial control circuits. Its bidirectional counting capability and easy cascading make it a versatile choice for both simple counters and complex multi-stage counting systems.
Where can I buy the SN74HC193D and what is the price?
