The Texas Instruments DM74LS169AN is a synchronous, presettable 4-bit up/down binary counter designed for high-speed counting applications. Its synchronous operation ensures all flip-flops are clocked simultaneously, eliminating output counting spikes common in ripple counters. The counter includes internal carry look-ahead circuitry, facilitating cascading for n-bit synchronous systems without additional gating.
Key features include a buffered clock input that triggers on the rising edge, and diode-clamped inputs to minimize transmission-line effects. The device is fully programmable, allowing outputs to be preset high or low. The direction of the count is controlled by the up/down input, with high indicating count up and low indicating count down. Both count-enable inputs (P and T) must be low for counting to occur.
This counter operates within a 0°C to 70°C free air temperature range and has a maximum supply and input voltage of 7V. It is available in a N16E package and is designed for through-hole mounting.

The DM74LS169AN is a Synchronous 4-Bit Up/Down Binary Counter.
The operating free air temperature range for the DM74LS169AN is 0°C to +70°C.
The maximum supply voltage for the DM74LS169AN is 7V.
Yes, the DM74LS169AN features internal carry look-ahead circuitry that permits cascading counters for n-bit synchronous applications.
The direction of the count is determined by the level of the up/down input. When the input is high, the counter counts up; when low, it counts down.
