74ALVC162834ADGG:1

Overview

The Nexperia 74ALVC162834ADGG:1 is an 18-bit registered driver featuring inverted register enable and integrated 30 Ω termination resistors. It operates within a supply voltage range of 1.2 V to 3.6 V, with recommended speeds up to 2.7 V at 30 pF load or 3.3 V at 50 pF load. The device provides current drive capability of ±12 mA at 3.0 V and supports 50 Ω transmission lines at 85°C. Propagation delay ranges from 1.0 ns to 5.4 ns depending on voltage. It utilizes a TSSOP56 package (SOT364-1) and functions across an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated 30 Ω series termination resistors in output stages for signal integrity
• MULTIBYTE flow-through standard pin-out architecture for simplified PCB layout
• Low inductance multiple VCC and GND pins designed to minimize noise and ground bounce
• Diode clamps on all inputs to accommodate strong drivers and protect against overvoltage

Applications

• High-speed data bus interfaces requiring registered buffering
• Systems driving 50 Ω transmission lines at elevated temperatures
• Applications utilizing mixed voltage domains between 2.7 V and 3.6 V

Procurement Notes

Verify the specific ordering suffix :1 corresponds to the required tape and reel packaging configuration. Confirm that the TSSOP56 package variant matches the footprint requirements of the target design. Ensure the operating environment remains within the specified -40 °C to +85 °C temperature range to maintain performance specifications.

Selection Notes

Select this component when an 18-bit registered buffer with built-in termination is required. The ALVC series offers direct interface compatibility with TTL levels in the 2.7 V to 3.6 V range. Consider the low inductance power pin arrangement if minimizing ground bounce is critical for system stability during high-frequency switching operations.

Part Context

This device belongs to the Nexperia 74ALVC logic family, which combines advanced CMOS technology with low power consumption. It serves as a registered driver solution, distinct from simple buffers by incorporating latch/flip-flop functionality controlled by clock and enable inputs. The inclusion of termination resistors differentiates it from standard line drivers in high-speed digital applications.

Replacement Considerations

Check for 74ALVC162834 variants without the :1 suffix if bulk packaging differs. Verify cross-reference availability from other manufacturers offering 18-bit registered drivers with similar pinouts and termination features.
