Counter Dividers datasheet and documents for SN74ALS561ANS

SN74ALS561ANS

Counter Dividers Overview

The SN74ALS561ANS is a synchronous 4-bit binary counter with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 30 MHz. The device features asynchronous and synchronous clearing, as well as loading capabilities. Propagation delays from the clock to any output range from 4 ns to 21 ns depending on conditions. Internal look-ahead circuitry facilitates fast cascading via ripple-carry (RCO) and clocked carry (CCO) outputs.

Counter Dividers Feature Summary

Supports both asynchronous and synchronous clearing and loading functions for flexible control.
Features internal look-ahead circuitry designed to enable high-speed cascading operations.
Provides buffer-type 3-state outputs capable of driving bus lines directly.

Counter Dividers Applications

Synchronous binary counting applications
High-speed digital timing circuits
Cascaded multi-stage counter systems

Counter Dividers Procurement Notes

Verify the specific package suffix 'N' corresponds to the Plastic Dual In-Line Package (PDIP-20) required for your design. Confirm that the 'S' in the ordering suffix aligns with the requested packaging format or distributor coding standards. Ensure the component meets the commercial temperature range specifications of 0°C to 70°C for your intended operating environment before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with 3-state outputs is required. It is suitable for designs needing internal look-ahead for faster cascading compared to standard ripple counters. Consider the ALS logic family characteristics regarding power consumption and speed relative to other TTL-compatible families available from Texas Instruments.

Counter Dividers Part Context

This part belongs to the SN74ALS series of logic integrated circuits produced by Texas Instruments. The ALS (Advanced Low-Power Schottky) family offers improved speed and power dissipation characteristics compared to earlier LS logic families. This specific model provides synchronous counting functionality with versatile control inputs for system integration.
