Frequently Asked Questions
What type of counter is the SN74HC193NG4?
The SN74HC193NG4 is a 4-bit synchronous up/down binary counter that can count in both directions using separate UP and DOWN clock inputs. It supports parallel load for presetting any starting value and provides carry and borrow outputs for cascading with additional counter stages.
What logic family does the SN74HC193NG4 belong to?
The SN74HC193NG4 belongs to the HC (High-speed CMOS) logic family, offering wide supply voltage range (typically 2V to 6V), high noise immunity, and low power consumption compared to older TTL logic families, while maintaining compatibility with standard CMOS and TTL logic levels.
What package does the SN74HC193NG4 use?
The SN74HC193NG4 comes in a 16-pin through-hole DIP (Dual In-Line Package), which is well suited for breadboard prototyping, educational projects, and through-hole PCB assembly where ease of handling and socketing is important.
Can the SN74HC193NG4 be cascaded for wider counters?
Yes, the SN74HC193NG4 provides dedicated carry (TCU) and borrow (TCD) outputs that can be connected to the clock inputs of additional counter ICs, allowing designers to cascade multiple devices to build 8-bit, 12-bit, or wider synchronous counters.
What are typical applications for the SN74HC193NG4?
Typical applications include event counters, frequency dividers, address generators, digital timers, and sequencer circuits in industrial electronics, test equipment, and educational digital logic boards that require flexible up/down counting with parallel load capability.
