Product Overview: 74HCT163DB from NXP

The 74HCT163DB is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. The 74HCT163DB is a 4-bit binary counter with a synchronous reset and is part of NXP Semiconductors' 74HCT range of integrated circuits.

Key Features

• Synchronous Counting and Loading: The counter advances on the rising edge of the clock (CLK) input. Synchronous operation is provided by having all flip-flops clocked simultaneously, so the outputs change together when so instructed by the steering logic.
• High-Speed Performance: The 74HCT163DB operates at a frequency of up to 48 MHz, providing high-speed counting for a variety of applications.
• Low Power Consumption: This device combines the low power advantages of CMOS with the high-speed and driving capacity of LSTTL.
• Multiple Operating Modes: It includes features such as look-ahead carry for high-speed counting and features two outputs (Q3, TC) for cascading.
• Wide Operating Voltage: It can operate at a voltage range of 4.5V to 5.5V, making it versatile for use in different circuit environments.
• Output Capability: The device features standard outputs that can drive up to 10 LSTTL loads.
• Synchronous Reset: A LOW level at the Master Reset (MR) input overrides all other inputs and forces the outputs LOW.

Applications

The 74HCT163DB is suitable for use in a wide range of applications, including:

• Industrial control systems
• Instrumentation
• Computer systems
• Counting operations
