74AVC16836ADGG,118

Overview

The Nexperia 74AVC16836ADGG,118 is a 20-bit universal bus driver featuring registered outputs and Dynamic Controlled Output (DCO) circuitry. It operates within a supply voltage range of 1.2 V to 3.6 V and complies with JEDEC standards for low-voltage applications. The device utilizes a TSSOP56 package (SOT364-1) and supports an operating temperature range from -40 °C to +85 °C. Propagation delay varies by voltage: typical values are 2.4 ns at 1.65 V–1.95 V, 1.7 ns at 2.3 V–2.7 V, and 1.5 ns at 3.0 V–3.6 V.

Feature Summary

• Dynamic Controlled Output (DCO) circuitry dynamically adjusts output impedance to reduce noise without degrading speed.
• Low inductance multiple VCC and GND pins minimize noise and ground bounce during operation.
• Power-off state disables outputs to permit live insertion when OE is tied to VCC via a pullup resistor.
• Integrated input diodes minimize input overshoot and undershoot events.

Applications

• Universal bus driver applications requiring registered data flow control.
• Termination line drive support during transient states.
• Mixed voltage environments utilizing inputs/outputs tolerant up to 3.6 V.

FAQ

How does the Dynamic Controlled Output (DCO) function?

The DCO circuit initially lowers the output impedance to effectively drive the load during transitions and subsequently raises the impedance to reduce noise.

What is the purpose of the inverted register enable (LE)?

The LE input is active LOW. When LE is low, data on the clock (CP) edge is latched into the outputs. When LE is high, the outputs retain their previous state regardless of CP changes.
