74LVC169BQ,115

Counter Dividers Overview

The NXP USA Inc. 74LVC169BQ,115 is a synchronous presettable 4-bit binary up/down counter featuring internal look-ahead carry circuitry for high-speed cascading. It operates within a supply voltage range of 1.2 V to 3.6 V and accepts 5 V tolerant inputs. The device uses edge-triggered J-K flip-flops triggered on the LOW-to-HIGH clock transition. It supports parallel load, count up, count down, and hold modes via dedicated control pins. The component is housed in a DHVQFN16 package (SOT763-1) with dimensions of 2.5 x 3.5 x 0.85 mm.

Counter Dividers Feature Summary

• Synchronous operation eliminates output counting spikes associated with asynchronous counters
• Internal look-ahead carry circuitry enables efficient n-bit cascading without additional gating
• Fully programmable with synchronous parallel preset capability for any number between 0 and maximum count
• Directional control allows configurable up or down counting sequences

Counter Dividers Applications

• High-speed synchronous counting applications requiring precise timing
• Cascaded multi-stage binary counter designs utilizing terminal count outputs
• Programmable logic systems requiring presettable initial states
• Digital circuits interfacing with 5 V logic using 5 V tolerant input levels

Counter Dividers Procurement Notes

Verify the specific ordering suffix matches the required temperature range and package variant. Confirm that the DHVQFN16 footprint aligns with PCB layout constraints. Ensure design compliance with JEDEC standards for the intended supply voltage node. Check current product status as specifications may be subject to revision.

Counter Dividers Selection Notes

Select this component when synchronous counting with minimal propagation delay is required. The built-in look-ahead carry reduces external gate requirements for multi-bit expansion. Verify input voltage compatibility if interfacing with TTL level signals. Consider the thermal performance characteristics of the leadless package for power dissipation limits.
