Product Overview: 74HC192D from NXP
The 74HC192D is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). Manufactured by NXP Semiconductors, this integrated circuit is part of the 74HC family, which is renowned for its robust performance and compatibility with a wide range of applications. The 74HC192D is specifically designed as a presettable synchronous up/down counter that has the capability to count in both ascending and descending order.
Key Features
- Logic Type: Synchronous Up/Down Counter
- Output Capability: Standard
- IC Output Type: Differential
- Supply Voltage Range: 2.0V to 6.0V
- Counting Sequence: Up/Down
- Operating Temperature Range: -40°C to +125°C

The device features a dual-clock with a master reset, allowing for precise control over the counting sequence. The synchronous operation is provided by having all flip-flops clocked simultaneously on the rising edge of the clock (CP). The 74HC192D comes with multiple inputs, including two count enable inputs (nCEP, nCET) and two up/down count inputs. This enables the circuit to be used in a variety of configurations and applications.
It also includes an overriding asynchronous master reset input (MR) and four buffered parallel outputs (Q0 to Q3). This device can be used in conjunction with other counters for extended counting range, and its multiple features make it suitable for a variety of applications including counters for clocks, timers, and frequency dividers.
The 74HC192D is housed in a 16-pin plastic SO package, which is a compact form factor that is suitable for space-constrained applications. The robust temperature range ensures that the device can operate in various environmental conditions, making it ideal for industrial and automotive applications.
In summary, the NXP 74HC192D is a versatile, reliable, and efficient solution for designers looking for an up/down counter with synchronous operation and a broad supply voltage range. Its compatibility with LSTTL levels, along with its presettable count capability, makes it a popular choice for digital logic systems.
