74ALVC08M

Overview

The onsemi 74ALVC08M is a quad 2-input AND gate manufactured using low-voltage silicon-gate CMOS technology. It operates within a supply voltage range of 1.65 V to 3.6 V and features Schmitt-trigger inputs for noise tolerance. The device provides 3.6 V tolerant inputs and outputs, enabling direct interfacing with TTL levels in mixed-voltage systems. Key electrical specifications include a propagation delay of 3 ns, output currents of ±24 mA, and an operating temperature range from -40°C to +85°C. It is housed in a TSSOP-14 surface-mount package.

Feature Summary

• Schmitt-trigger action at all inputs ensures tolerance for slower input rise and fall times.
• I_OFF circuitry supports partial power-down mode by disabling outputs to prevent damaging backflow current.
• Inputs are overvoltage tolerant up to 3.6 V, allowing direct interface with TTL logic levels.

Applications

• Mixed 3.3 V and 5 V system translation
• High-speed data bus applications
• Partial power-down mode operation

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and environmental declarations prior to integration. Check for active production status or obsolescence notices, as availability may vary by region. Ensure ESD handling protocols are followed during assembly.

Selection Notes

Select this component when designing low-voltage digital circuits requiring high drive capability and noise immunity. The Schmitt-trigger inputs make it suitable for noisy environments or signals with slow transitions. Verify that the 3.6 V I/O tolerance aligns with the target system voltage levels to ensure reliable signal integrity without additional level shifting components.

Part Context

This part belongs to the 74ALVC series of advanced low-voltage CMOS logic gates. It is functionally equivalent to other manufacturers' 74ALVC08 devices but utilizes onsemi's specific manufacturing processes. The 'M' suffix typically denotes the TSSOP-14 package variant, distinguishing it from SOIC or other package options within the same logical family.

Replacement Considerations

Direct substitutes include the Nexperia 74ALVC08D and Fairchild Semiconductor 74ALVC08. These alternatives share identical logical functions and pinouts. Verify package dimensions and thermal characteristics when swapping between different manufacturers to ensure mechanical compatibility.

FAQ

Does the 74ALVC08M support partial power-down?

Yes, the device includes I_OFF circuitry that disables the outputs when powered down, preventing potentially damaging backflow current through the device.

What is the maximum input voltage tolerance?

The inputs are tolerant up to 3.6 V, allowing them to be driven by 3.3 V or 5 V devices while the core operates at lower voltages.
