Product Introduction

Overview

The CD74HC93MT, produced by Texas Instruments, is a high-speed silicon-gate CMOS logic 4-bit binary ripple counter. This device is part of the 74HC series and is pin-compatible with low power Schottky TTL (LSTTL) logic ICs. It consists of four flip-flops internally connected to provide a divide-by-two section and a divide-by-eight section, each with separate clock inputs (CP0 and CP1) to initiate state changes on the HIGH to LOW clock transition. The counter is designed for asynchronous reset and features a wide operating temperature range from -55°C to 125°C.

Key Features

  • Can be configured to divide by 2, 8, and 16.
  • Asynchronous reset capability.
  • Fanout (over temperature range): Standard outputs can drive 10 LSTTL loads, and bus driver outputs can drive 15 LSTTL loads.
  • Wide operating temperature range: -55°C to 125°C.
  • Significant power reduction compared to LSTTL logic ICs.
  • High noise immunity: NIL = 30%, NIH = 30% of VCC for HC types, and direct LSTTL input logic compatibility for HCT types.
  • CMOS input compatibility with low input current (II ≤ 1 µA at VOL, VOH).

Applications

  • General-purpose counting and timing applications.
  • Frequency division in digital circuits.
  • Sequential logic circuits requiring asynchronous reset.
  • High-speed digital systems where low power consumption and high noise immunity are crucial.
  • Automotive and industrial control systems due to its wide operating temperature range.
