Product Overview: 74HCT193N by NXP

The 74HCT193N is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). Manufactured by NXP Semiconductors, it is part of the 74HCT series known for combining the best features of both TTL and CMOS technologies. This integrated circuit is a 4-bit synchronous binary up/down counter that offers robust performance for a wide range of digital applications.

Key Features

• Synchronous Counting: The 74HCT193N features synchronous reversible 4-bit binary counting, which allows for precise control and predictable timing of the counting sequence.
• Dual Clock Inputs: With two separate clock inputs, one for the up-count and another for the down-count, this device provides flexibility in controlling the count sequence.
• Asynchronous Master Reset: An asynchronous master reset input (MR) is available for initializing the counter to a pre-set value irrespective of the clock inputs.
• Multiple Count Enable Inputs: Count enable inputs for both up (CEP) and down (CET) counting modes allow the counter to be easily configured for various counting operations.
• Output Capability: The counter features standard outputs (Q0 to Q3) that can drive up to 10 LSTTL loads, ensuring compatibility with a variety of digital circuits.
• High Noise Immunity: True CMOS input and output buffering provide high noise immunity and low power consumption typical of CMOS devices, while still maintaining a LSTTL interface.
• Wide Operating Voltage: The device can operate at a wide range of voltages from 4.5V to 5.5V, making it versatile for use in various system voltages.
