Product details

Overview

74ALVT162245DL,118 from NXP Semiconductors is a 16-bit non-inverting bus transceiver with 3-state outputs, designed for bidirectional data flow between buses operating at different voltage levels (3.3 V and 5 V). It features ±24 mA output drive, 3.3 V LVT logic compatibility, and operates over –40 °C to +85 °C. Used in backplane interface and memory expansion subsystems.

For engineers reviewing the 74ALVT162245DL,118 datasheet, 74ALVT162245DL,118 pinout, 74ALVT162245DL,118 application, or 74ALVT162245DL,118 equivalent, key selection criteria include bus direction control timing, 3.3 V/5 V level translation capability, output drive strength, thermal performance in high-density PCB layouts, and industrial temperature range compliance.

Technical Context

This transceiver implements dual 8-bit bidirectional channels with independent OE# and DIR controls per byte group. Each channel supports hot insertion via Ioff protection and power-off isolation when VCC = 0 V.

It uses ALVT (Advanced Low-Voltage TTL) technology enabling 3.3 V operation while maintaining TTL-compatible thresholds and 5 V tolerant inputs. Propagation delay is typically 2.8 ns at VCC = 3.3 V, supporting >300 MHz data rates in point-to-point configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	ALVT - enables 3.3 V supply operation with 5 V-tolerant inputs and TTL-compatible thresholds
Data Width	16-bit (dual 8-bit) - supports parallel data transfer across two independent byte lanes
Output Drive	±24 mA - sufficient to drive 50 Ω transmission lines or multiple LVTTL loads without external buffering
Propagation Delay	2.8 ns (typ.) - allows reliable operation up to 300 MHz in short-trace, low-capacitance environments
Operating Temperature	–40 °C to +85 °C - qualified for industrial-grade embedded systems and telecom infrastructure
Ioff Protection	Enabled - prevents current backflow during power-down, supporting live insertion in modular backplanes

Pinout & Package

Supplied in 48-pin TSSOP (Thin Shrink Small Outline Package) with 0.5 mm pitch, JEDEC MO-153 compliant, body size 12.5 × 6.1 mm, 1.2 mm max height. Designed for fine-pitch surface-mount assembly and thermal dissipation in multi-layer PCBs.

Pin/Terminal	Circuit Role	Design Meaning
A0–A7	Input/Output Port A (lower byte)	Bidirectional data lane; driven by B-side when DIR = HIGH, high-impedance when OE# = HIGH
B0–B7	Input/Output Port B (upper byte)	Bidirectional data lane; driven by A-side when DIR = LOW, high-impedance when OE# = HIGH
DIR	Direction Control Input	Active-HIGH signal sets data flow from A→B; active-LOW sets B→A; asynchronous control
OE#	Output Enable (active-low)	Disables both A and B ports simultaneously into high-impedance state; supports bus sharing
VCC	Supply Voltage	3.3 V nominal (3.0–3.6 V); powers internal logic and output drivers
GND	Ground Reference	Common return path for all I/O and core logic; requires low-inductance connection to plane

Key Features

Feature	Design Value
5 V-tolerant inputs	Accepts 0–5.5 V input signals while powered from 3.3 V, enabling mixed-voltage system interfacing
Live-insertion support	Ioff circuitry blocks current flow when VCC = 0 V, allowing safe board replacement in powered-backplane systems
Bus-hold circuitry	Internal weak pull-up/pull-down on all I/O pins eliminates need for external resistors in floating-bus scenarios
Flow-through pinout	A and B port pins aligned on opposite sides of package - simplifies layer routing and reduces crosstalk in dense PCB layouts

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar bus transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC16245ADGGR	3.3 V only (not 5 V tolerant), lower drive (±24 mA same), no Ioff	Suitable for 3.3 V-only systems; lacks live-insertion capability	Select when cost sensitivity outweighs hot-swap requirement and voltage translation is unnecessary
74LVTH162245DGGR	Same pinout and function but uses LVTH logic; 3.3 V supply, 5 V tolerant, no Ioff	Compatible in footprint and logic behavior, but not qualified for hot insertion	Choose if existing layout uses DGGR package and Ioff is not required for the application

Compared with SN74LVC16245ADGGR and 74LVTH162245DGGR, the 74ALVT162245DL,118 uniquely delivers 5 V tolerance, Ioff protection, and industrial temperature rating in a single TSSOP-48 package-critical for backplane and mixed-voltage upgrade paths.

FAQ

What is the maximum clock frequency supported by the 74ALVT162245DL,118?

The device does not operate on a clock; it is an asynchronous transceiver. Its usable data rate depends on propagation delay (2.8 ns typical) and system trace capacitance. In controlled-impedance 50 Ω environments with ≤10 pF load, it reliably supports data transitions exceeding 300 MHz.

Can the 74ALVT162245DL,118 be used for unidirectional signal translation only?

Yes. By holding DIR constant (HIGH for A→B or LOW for B→A) and using OE# to enable/disable the path, the device functions as a unidirectional translator. Its 5 V-tolerant inputs allow 5 V signals to be safely translated to 3.3 V logic levels on the driven side.

Does the 74ALVT162245DL,118 require external pull-up or pull-down resistors on its I/O pins?

No. All I/O pins integrate bus-hold circuitry that maintains last-valid logic state when inputs float. This eliminates the need for external biasing resistors in most applications, reducing BOM count and PCB area.

Is the 74ALVT162245DL,118 RoHS compliant and lead-free?

Yes. The 74ALVT162245DL,118 is manufactured in a lead-free process and complies with EU RoHS Directive 2011/65/EU and JEDEC JS-066 standards. The "118" suffix denotes tape-and-reel packaging with RoHS-compliant finish.
