• High-speed registered drivers

Procurement Notes

Verify the manufacturer origin as Philips Semiconductors or NXP. Confirm the package type is 56-pin TSSOP Type II (SOT364-1). Ensure the temperature range matches -40 °C to +85 °C. Check RoHS compliance status against current environmental regulations before procurement.

Selection Notes

Select this component for designs requiring fast propagation delay and minimal power consumption. It is suitable for live insertion scenarios when OE is tied to VCC via a pullup resistor. Ensure the application utilizes compatible clock distribution devices like PCK2510S for optimal performance.

Part Context

This part belongs to the 74AVCM logic family, designed for high-speed digital applications. It functions as a registered driver with latch enable and clock inputs. The device is intended to reduce signal loads on memory controllers and prevent timing delays in complex digital systems.

Replacement Considerations

Check for direct equivalents within the 74AVCM series. Verify pin compatibility and electrical characteristics if substituting with other 18-bit registered drivers. Ensure the replacement supports the required 1.2 V to 3.6 V operating range.

FAQ

How does the device ensure high-impedance state during power-up?

The OE input should be tied to VCC through a pullup resistor to ensure the high-impedance state during power-up or power-down.

What is the maximum clock pulse frequency?

The maximum clock pulse frequency varies by voltage; it is 500 MHz at 3.3 V, 400 MHz at 2.5 V, and 250 MHz at 1.8 V.
