Counter Dividers datasheet and documents for HEF4526BT,653

HEF4526BT,653

Counter Dividers Overview

The HEF4526BT,653 is a synchronous programmable 4-bit binary down counter manufactured by NXP Semiconductors. It features active HIGH and active LOW clock inputs (CP0, CP1), an asynchronous parallel load input (PL), four parallel inputs (A0 to A3), a cascade feedback input (CF), four buffered parallel outputs (Q0 to Q3), a terminal count output (TC), and an overriding asynchronous master reset input (MR). The device operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS. It complies with JEDEC standard JESD 13-B and is specified for operation from -40 °C to +85 °C.

Counter Dividers Feature Summary

Fully static operation with standardized symmetrical output characteristics
Schmitt trigger action on clock inputs provides high tolerance for slower rise and fall times
Supports divide-by-n applications via decoded TC output and cascade feedback input

Counter Dividers Applications

Divide-by-n counter circuits
Programmable frequency divider designs
Multi-stage cascaded counting systems

Counter Dividers Procurement Notes

Verify the specific package variant against the required footprint, as the HEF4526B family includes both DIP16 (SOT38-4) and SO16 (SOT109-1) options. Confirm that the ordering suffix matches the intended physical package type. Ensure design compliance with the absolute maximum ratings regarding supply voltage and current limits to prevent permanent damage.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit down counter with dual clock inputs and programmable preset capabilities is required. The inclusion of Schmitt trigger inputs makes it suitable for environments with noisy or slow-rising clock signals. Verify that the operating voltage range of 3 V to 15 V aligns with the system power supply requirements.

Counter Dividers Part Context

This part belongs to the HEF4526B logic family, which consists of synchronous programmable 4-bit binary down counters. The 'BT' designation in the model number specifically indicates the SO16 plastic small outline package variant (SOT109-1), distinguishing it from the DIP16 version.
