74HC4538PW-Q100,11

Overview

The Nexperia 74HC4538PW-Q100,11 is a dual retriggerable-resettable monostable multivibrator in the HC logic series. It operates within a supply voltage range of 2.0 V to 6.0 V and is housed in a TSSOP16 (SOT403-1) package with 16 leads. Qualified under AEC-Q100 Grade 1 standards, it supports ambient temperatures from -40 °C to +125 °C. Each multivibrator features two trigger inputs, a direct reset input, complementary outputs, and external timing pins for precise pulse width control.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Dual precision monostable multivibrators with separate reset inputs
• Tolerant of slow trigger rise and fall times via Schmitt-trigger action
• Capable of triggering from both positive and negative signal edges

Applications

• Automotive electronic systems requiring qualified logic components
• Timing circuits utilizing external resistor and capacitor networks
• Pulse generation and waveform shaping applications

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when automotive reliability is required alongside dual independent timing channels. The TSSOP16 package suits space-constrained designs. Ensure external timing components are chosen to meet specific pulse width requirements, as duration depends on REXT and CEXT values. Verify interface compatibility with CMOS input levels across the target operating temperature range.

Part Context

This device belongs to the Nexperia 74HC4538-Q100 family of dual retriggerable monostable multivibrators. It shares functional characteristics with other variants like the SO16 packaged 74HC4538D-Q100 but differs in physical footprint. The product line emphasizes high noise immunity and low power dissipation typical of CMOS technology.

Replacement Considerations

The 74HC4538D-Q100 serves as a functional substitute using an SO16 package instead of TSSOP16. Other non-automotive grade 74HC4538 devices may offer similar electrical performance but lack the specified AEC-Q100 qualification.
