ON Semiconductor MC74F169D Product Overview

The MC74F169D from ON Semiconductor is a high-performance, 4-bit synchronous up/down binary counter integrated circuit, designed to operate in a multitude of counting and sequencing applications. This versatile device is fabricated with advanced silicon-gate BiCMOS technology, combining the speed of bipolar with the low power of CMOS to deliver a robust and efficient performance.

Key Features

• Synchronous Counting: The MC74F169D operates synchronously, with all state changes occurring on the rising edge of the clock signal, ensuring precise timing and control in high-speed counting applications.
• Up/Down Counting Capability: It can count in both directions, allowing for versatile counting sequences. The direction of the count is determined by the state of the UP/DOWN input.
• Loadable Counter: The counter can be preset to any desired value by applying the value to the data inputs (D0-D3) and taking the parallel enable (PE) input low.
• Master Reset: The device includes a master reset (MR) function that clears the counter to its zero state when activated.
• Output Enable: The output enable (OE) function provides a means to place the outputs in a high-impedance state, which is useful for interfacing with bus-oriented systems.
• Carry Lookahead: For cascading multiple counters, the terminal count (TC) output can be used to enable lookahead carry or borrow for high-speed counting chains.
• Compact Packaging: The MC74F169D comes in a 16-pin SOIC package, making it suitable for space-constrained applications.
