74ALVC16834ADGG,11

Overview

The Nexperia 74ALVC16834ADGG,11 is an 18-bit registered driver featuring inverted register enable and 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports direct interface with TTL levels at voltages from 2.7 V to 3.6 V. The device provides a current drive capability of ±24 mA at VCC = 3.0 V. Propagation delay ranges from 1.0 ns to 5.4 ns depending on the control signal and voltage. It utilizes a MULTIBYTE flow-through standard pin-out architecture in a TSSOP56 package.

Feature Summary

• Features active low latch enable (LE), output enable (OE), and clock pulse (CP) inputs for data flow control.
• Includes low inductance multiple VCC and GND pins designed to minimize noise and ground bounce.
• Provides input diodes to accommodate strong drivers and ensures high-impedance state during power up or down.

Applications

• Bus-oriented applications requiring 3-state non-inverting outputs
• Driving 50 Ω transmission lines at 85 °C
• Systems utilizing MULTIBYTE flow-through standard pin-out architecture

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm that the component meets JEDEC standards JESD8-5 and JESD8B/JESD36 for the intended operating voltage. Ensure design safeguards are implemented to manage ESD protection requirements as specified in the datasheet.

Selection Notes

Select this component for designs requiring 18-bit registered driving with inverted register enable. It is suitable for applications needing direct TTL level interfacing and robust current drive capabilities. Verify that the operating temperature range of -40 °C to +85 °C aligns with system environmental constraints.

FAQ

How does the OE input affect the latch state?

Operation of the OE input does not affect the state of the latch/flip-flop; it only controls whether the outputs are active or in a high-impedance OFF-state.

What is the function of the LE input?

When LE is LOW, the A to Y data flow is transparent. When LE is HIGH and CP is held at LOW or HIGH, the data is latched.
