SN74F169D

Counter Dividers Overview

The SN74F169D is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments in a 16-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features internal look-ahead circuitry for high-speed cascading, with maximum clock frequencies reaching 100 MHz at 5V. Propagation delays from clock to output range from 2.2 ns to 13 ns depending on conditions.

Counter Dividers Feature Summary

• Fully synchronous operation eliminates counting spikes associated with asynchronous counters
• Internal carry look-ahead circuitry enables fast n-bit cascading without additional gating
• Programmable preset capability allows loading any value between zero and maximum count

Counter Dividers Applications

• High-speed synchronous counting applications
• N-bit cascaded counter systems
• Programmable timing circuits

Counter Dividers Procurement Notes

Verify the specific datasheet revision and package marking against the official Texas Instruments documentation prior to procurement. Confirm that the component meets the required electrical specifications for your application environment. Ensure compatibility with your system's voltage levels and signal integrity requirements before finalizing orders.

Counter Dividers Selection Notes

Select this component when synchronous counting behavior is required to prevent output glitches. The internal look-ahead feature makes it suitable for designs needing high-frequency performance beyond standard ripple counters. Consider the 16-pin SOIC package constraints and thermal characteristics for your board layout.
