Product details

Overview

74ALVC162834ADGG:1 from Nexperia is an 18-bit registered bus driver with inverted latch enable (LE), active-low 3-state output enable (OE), edge-triggered clock (CP), and integrated 30 Ω series termination resistors on all outputs. It operates from 1.2 V to 3.6 V, delivers ±12 mA drive at 3.0 V, and supports high-speed data latching in memory interface and backplane bus applications.

For engineers reviewing the 74ALVC162834ADGG:1 datasheet, 74ALVC162834ADGG:1 pinout, 74ALVC162834ADGG:1 application, or 74ALVC162834ADGG:1 equivalent, key selection criteria include its multibyte flow-through TSSOP56 pinout, 30 Ω on-die termination for impedance matching, low-noise dual-VCC/GND architecture, and guaranteed 240 MHz max clock frequency at 3.3 V.

Technical Context

This device implements a synchronous 18-bit register with transparent/latched operation controlled by LE and CP: when LE is LOW, A-to-Y path is transparent; when LE is HIGH, data is captured on the LOW-to-HIGH CP edge. OE operates independently to place outputs in high-impedance state without affecting internal latch state.

The integrated 30 Ω series resistors are placed in both HIGH and LOW output stages, enabling direct drive of 50 Ω transmission lines at 85 °C without external termination. Diode clamps on all inputs and low-inductance multiple VCC/GND pins minimize ground bounce and support robust signal integrity in dense PCB layouts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 18-bit registered driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ALVCH162834DGGR	No integrated 30 Ω termination; requires external resistors; higher ICC (100 μA typical)	Suitable where board space permits discrete termination and lower static power is not critical	Select when cost-per-resistor is lower than premium for integrated termination
74LVC162244APAG	Non-registered (transparent only); no clock or latch inputs; 24-bit, not 18-bit	Applicable only in non-synchronous bus buffering where timing alignment is not required	Choose only if latching functionality is unnecessary and channel count flexibility is prioritized

Compared with SN74ALVCH162834DGGR and 74LVC162244APAG, the 74ALVC162834ADGG:1 uniquely combines 18-bit registered operation, on-die 30 Ω termination, and multivoltage support - making it optimal for space-constrained, high-speed synchronous bus interfaces where signal integrity and timing predictability are critical.

FAQ

What is the function of the inverted latch enable (LE) input?

The LE input is active-low: when LE is LOW, the device operates in transparent mode (A-to-Y path enabled); when LE is HIGH, data is latched on the rising edge of CP. This inversion allows direct connection to standard bus controllers that assert latch signals active-high, simplifying glue logic design without external inverters.

How does the integrated 30 Ω termination improve signal integrity?

The 30 Ω series resistor per output is designed to match the characteristic impedance of typical PCB traces when combined with load capacitance and line termination. It dampens reflections, reduces ringing, and enables clean edges on 50 Ω transmission lines - especially critical at 240 MHz operation and in backplane applications with long stubs.

Can OE be left floating during power-up?

No. To guarantee high-impedance outputs during power-up/power-down, OE must be tied to VCC via a pull-up resistor. The minimum value depends on the driver's current-sinking capability (typically ≥10 kΩ). Floating OE may cause undefined output states and bus contention in multi-driver systems.

Is this device suitable for automotive applications?

No. The 74ALVC162834ADGG:1 is not automotive-qualified. It is rated for −40 °C to +85 °C industrial operation but lacks AEC-Q100 qualification, automotive-grade screening, or extended temperature validation. For automotive use, consult Nexperia's automotive-qualified ALVC variants with explicit AEC-Q100 certification.
