Texas Instruments CD4541BE CMOS Programmable Timer DIP-14

The Texas Instruments CD4541BE is a CMOS programmable timer IC in a 14-pin DIP package, supporting a supply range of 3 V to 18 V.

Overview

The CD4541BE is a high-voltage CMOS programmable timer integrated circuit housed in a 14-pin DIP (Dual In-line Package). It is designed for timing applications where programmable control is achieved through external components. At its core, the device contains a 16-stage binary counter and an oscillator controlled by two external resistors and a capacitor, allowing time intervals to be configured flexibly. The listed dimensions are 3.3 (width), 1.5 (depth) and 4.3 (height), with a weight of 0.907 g.

Key Features

• Automatic power-on reset circuit for reliable startup
• Output control logic that selects the 8th, 10th, 13th or 16th counter stage via time select inputs A and B
• Output configurable as Q or Q (complement), selectable via the MODE input
• Two operating modes selectable via the MODE input
• MASTER RESET and AUTO RESET inputs for counter control and timing initialisation
• Oscillator frequency range from DC up to 100 kHz, with an option to apply an external clock signal directly to Pin 3
• Symmetrical output characteristics with low output resistance, typically 100 ohms at a 15 V supply
• Rated for 5 V, 10 V and 15 V parametric operation, with a 20 V high-voltage rating and quiescent current tested at 20 V
• Operating temperature range from -55°C to +125°C

Applications

The device can operate as a precise 2^N frequency divider or as a single-transition timer for pulse generation, making it suitable for a wide array of timing applications.

Handling Note

This device is sensitive to electrostatic discharge (ESD). Follow proper IC handling procedures to prevent damage.
