M74HC4538RM13TR Description

Short technical summary and product information.

The M74HC4538RM13TR from STMicroelectronics is a high-speed CMOS monostable multivibrator designed for versatile timing applications. Fabricated using silicon gate C2MOS technology, this device offers excellent performance characteristics, including a typical propagation delay of 25 ns at 6V and low power dissipation.

Each multivibrator within the M74HC4538 features both negative and positive edge-triggered inputs, which can also function as inhibit inputs. A direct reset input is available for immediate output termination. The device is retriggerable, allowing for pulse width extension by repeated triggering.

The output pulse width is determined by the external components R and C, following the equation PW = 0.7 (R)(C). This allows for flexible pulse width generation from 120 ns to 60 seconds. The operating voltage range is from 2V to 6V, making it suitable for various system designs.

Packaged in an SOP, the M74HC4538RM13TR is pin and function compatible with the 74 Series 4538. All inputs are protected against static discharge and transient overvoltage, enhancing reliability.
