74ALVC16334ADGG:11

Overview

The 74ALVC16334ADGG:11 is a 16-bit registered driver with inverted register enable and 3-state outputs, housed in a 48-pin TSSOP package. It operates within a supply voltage range of 1.2 V to 3.6 V. At 3.0 V, it provides current drive of ±24 mA and supports propagation delays as low as 2.3 ns with a maximum clock frequency of 350 MHz at 3.3 V. The device features low power consumption, direct TTL level interface capability, and compliance with JEDEC standard no. 8-1A.

Feature Summary

• Provides 16-bit data registration controlled by active low latch enable and clock inputs
• Features 3-state outputs managed by an active low output enable signal
• Supports wide supply voltage operation from 1.2 V to 3.6 V
• Includes low inductance multiple VCC and GND pins for noise reduction

Applications

• Universal bus driving applications requiring registered data storage
• High-speed data transmission line interfacing
• Systems requiring direct interface with TTL logic levels
• Multi-byte flow-through architecture implementations

Procurement Notes

Verify the specific ordering code 74ALVC16334ADGG:11 against the manufacturer's latest documentation to ensure compatibility with required temperature ranges and package types. Confirm that the 48-pin TSSOP form factor matches the target PCB footprint. Ensure design specifications align with the recommended operating conditions provided in the official datasheet before finalizing procurement decisions.

Selection Notes

Select this component when a 16-bit registered driver with 3-state outputs is required for high-speed data bus applications. Consider the 1.2 V to 3.6 V supply range for flexibility in low-voltage systems. Evaluate the ±24 mA drive capability at 3.0 V for driving 50 Ω transmission lines. Verify that the TSSOP48 package fits the available board space and thermal requirements.

Part Context

This part belongs to the 74ALVC16334A family of 16-bit registered drivers originally specified by Philips Semiconductors. The 'DGG' suffix indicates the 48-pin Plastic Thin Shrink Small Outline (TSSOP) Type II package. The ':11' suffix denotes a specific reel or tape configuration for automated assembly. The device replaces earlier versions of the 74ALVC16334 specification.

Replacement Considerations

Check for updated revisions of the 74ALVC16334A series which may have superseded the original Philips specification. Verify pinout compatibility if substituting with equivalent parts from other manufacturers offering 16-bit registered drivers in TSSOP48 packages.

FAQ

How is the high-impedance state ensured during power up or power down?

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

What determines the minimum value of the pullup resistor on the OE input?

The minimum value of the resistor is determined by the current-sinking capability of the driver.

Does the operation of the OE input affect the state of the latch/flip-flop?

No, the operation of the OE input does not affect the state of the latch/flip-flop.
