Product Overview: 74HC160T from NXP Semiconductors

The 74HC160T is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). It is fabricated with silicon gate CMOS technology which ensures a robust and reliable design. This particular integrated circuit is part of the 74HC/HCT family, known for its ease of use in a wide range of digital applications.

Key Features

• Logic Type: Synchronous Counter
• Output Type: Differential
• Counting Sequence: Up
• Propagation Delay Time: 18 ns at 4.5 V, 16 ns at 6 V
• Operating Temperature Range: -40°C to +125°C
• Supply Voltage Range: 2 V to 6 V
• Package: SMD/SMT

The 74HC160T is designed for asynchronous presetting and synchronous counting. The asynchronous parallel load capability permits the counter to be preset to any desired value. This feature can be initiated by a high level on the preset enable input (PE). When PE is low, data on the D0 to D3 inputs is ignored. The counter is incremented on the positive-going transition of the clock input (CP) when the clock enable input (CEP) is low and the count enable input (CET) is high.

The 74HC160T includes a carry output (RCO) which provides a ripple carry signal to enable cascaded counters. The maximum clock frequency typically exceeds 100 MHz, and the device has a low power consumption. This makes the 74HC160T suitable for a variety of applications ranging from high-speed systems to battery-powered products.

Applications

The versatility of the 74HC160T makes it suitable for a wide array of applications, including:

• Timing circuits
