Overview
The CD14538BM96 is a CMOS Dual Precision Monostable Multivibrator produced by Texas Instruments. This component is designed to provide stable, retriggerable/resettable one-shot operation for various fixed-voltage timing applications. It operates over a wide temperature range of -55°C to 125°C, making it suitable for diverse environmental conditions. The CD14538BM96 is available in a 16-pin SOIC (D) package and is interchangeable with the MC14538 and similar to the CD4098B and CD4538B, although it is recommended over the CD4538B for new designs.

Q & A
- What is the operating temperature range of the CD14538BM96?
The CD14538BM96 operates over a temperature range of -55°C to 125°C.
- What package types are available for the CD14538B series?
The CD14538B series is available in 16-lead hermetic dual-in-line ceramic packages, 16-lead dual-in-line plastic packages, 16-lead small-outline packages, and 16-lead thin shrink small-outline packages.
- How is the output pulse width controlled in the CD14538BM96?
The output pulse width is controlled by an external resistor (RX) and an external capacitor (CX). The time period (T) can be calculated using the formula T = RXCX.
- What are the minimum and maximum values for the external capacitance (CX)?
The minimum value for CX is 0 pF, and the maximum value is 100 µF.
- Can the CD14538BM96 be triggered from both leading and trailing edges?
- What is the purpose of the Schmitt-trigger input in the CD14538BM96?
The Schmitt-trigger input allows for unlimited rise and fall times on the +TR and -TR inputs, enhancing noise immunity.
- Is the CD14538BM96 compatible with other Texas Instruments components?
- What are the typical applications of the CD14538BM96?
- What is the maximum input current of the CD14538BM96?
