74HC4538FP-E

Overview

The 74HC4538FP-E is a dual precision monostable multivibrator manufactured by Renesas Electronics Corporation. It is implemented in advanced silicon-gate CMOS technology, offering propagation delays of 25 ns. The device operates within a supply voltage range of 2 V to 6 V and features Schmitt trigger inputs for noise immunity. Each multivibrator includes positive and negative transition triggered inputs, an inhibit function, and a clear input for resetting the output pulse.

Feature Summary

• Dual retriggerable precision monostable multivibrators with Schmitt trigger inputs
• High-speed operation comparable to low power Schottky TTL circuitry
• Wide power supply range supporting 2 V to 6 V operation
• Low input current characteristics typical of CMOS circuits

Applications

• Digital timing and pulse generation circuits
• Frequency division applications
• Pulse width modulation systems
• Timing delay circuits requiring precise monostable triggering

Procurement Notes

Verify the specific suffix 'FP-E' against the manufacturer's official datasheet to confirm package type and RoHS compliance status. Ensure the ordering code matches the exact pinout and electrical specifications required for your design. Cross-reference with authorized distributors to confirm current availability and authenticity of the Renesas Electronics component.

Selection Notes

Select this component when dual independent monostable multivibrators are required in a compact surface-mount package. The HC logic series provides compatibility with standard digital interfaces while maintaining low power consumption. Consider the 25 ns propagation delay and 2-6 V operating range to ensure alignment with system voltage levels and timing requirements.

Part Context

This part belongs to the 74HC4538 family of dual precision monostable multivibrators. It is pin-compatible with other industry-standard variants like the CD4538. The FP-E designation typically indicates a specific plastic small outline package variant offered by Renesas Electronics for surface-mount assembly applications.

Replacement Considerations

Compatible substitutes include MM74HC4538 from ON Semiconductor or Fairchild, and TC74HC4538 from Toshiba. Verify that alternative sources offer identical pinouts and electrical characteristics before substitution.
