74ALVC162834ADGG,1

Overview

The Nexperia 74ALVC162834ADGG,1 is an 18-bit registered driver housed in a TSSOP56 (SOT364-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V and features integrated 30 Ω series termination resistors for signal integrity. The device provides 3-state outputs controlled by active low output enable (OE), latch enable (LE), and clock (CP) inputs. It supports direct interface with TTL levels at voltages between 2.7 V and 3.6 V and delivers a current drive capability of ±12 mA at 3.0 V.

Feature Summary

• Integrated 30 Ω series termination resistors in both HIGH and LOW output stages
• Active low latch enable (LE) and output enable (OE) control data flow and state retention
• Low inductance multiple power and ground pins designed to minimize noise and ground bounce
• Diode clamps on all inputs to accommodate strong drivers

Applications

• High-speed parallel data bus registration
• Memory interface circuits requiring registered buffering
• System applications utilizing 50 Ω transmission lines

Procurement Notes

Verify the specific ordering suffix ',1' corresponds to the required tape and reel packaging configuration. Confirm that the TSSOP56 package variant aligns with your PCB footprint requirements. Ensure the operating temperature range of -40 °C to +85 °C meets your environmental specifications before finalizing procurement.

Selection Notes

Select this component when an 18-bit registered driver with built-in termination is required. It is suitable for designs needing direct TTL interfacing at higher supply voltages. Consider the MULTIBYTE flow-through architecture if standard pin-out compatibility is necessary. Verify that the 3-state output behavior matches the system's bus management requirements.

Part Context

This part belongs to the ALVC logic family, characterized by high-speed performance and wide supply voltage operation. It serves as a registered driver solution within Nexperia's portfolio of advanced low-voltage CMOS technologies. The device complements other bus transceivers and buffers by providing latched data storage capabilities alongside signal driving functions.

Replacement Considerations

Direct replacements must match the 18-bit width, ALVC speed grade, and TSSOP56 package. Verify functional equivalence regarding the inverted register enable and 30 Ω termination integration.
