Overview
The Nexperia 74HCT7541D,118 is an octal Schmitt trigger buffer and line driver housed in a SO20 (SOT163-1) plastic small outline package. It features non-inverting outputs with two active-low output enable inputs (OE1, OE2) that force the outputs into a high-impedance OFF-state when asserted. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. Inputs include clamp diodes for interfacing with voltages exceeding VCC.
Feature Summary
- Schmitt-trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
- Dual active-low output enables provide flexible bus management control
- Input clamp diodes allow safe interfacing to voltages higher than the supply rail
Applications
- Bus-oriented communications systems
- Clock buffering and distribution
- Memory data bus drivers
Procurement Notes
Verify the specific ordering suffix matches the required package variant. Confirm the logic family designation aligns with system voltage requirements. Check the most recent datasheet revision for any updates to pinning or electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component when TTL-compatible input levels are required alongside Schmitt trigger noise immunity. Ensure the application environment remains within the specified -40 °C to +125 °C operating temperature range. Verify that the SO20 package dimensions fit the available PCB footprint constraints.
Part Context
This part belongs to the 74HCT series, which provides CMOS low power dissipation while maintaining TTL-compatible input thresholds. It is functionally equivalent to the 74HC7541 but optimized for 5 V operation. The D suffix indicates the SO20 package type.
Replacement Considerations
Direct functional replacements include other manufacturers' 74HCT7541 variants in SO20 packages. Verify pinout compatibility and ensure the substitute meets the same 3-state output and Schmitt trigger input specifications.
