Technical Specifications

The TC74HC4538P is a member of the HC (High-speed CMOS) logic family. The output pulse width is determined by the external resistor (R) and capacitor (C) connected to the timing pins. The pulse width is approximately equal to 0.7 x R x C. The device operates over a temperature range of -40°C to +85°C. The package type is a DIP-16 (Dual In-line Package). The propagation delay time is typically 15ns at a supply voltage of 5V. Refer to the Toshiba datasheet for detailed electrical characteristics and timing diagrams.
