Product details

Overview

74LVC162245ADGVJ from Nexperia is a 16-bit dual 8-bit transceiver with integrated 30 Ω series termination resistors, 3-state outputs, and independent direction (1DIR/2DIR) and output enable (1OE/2OE) controls. It operates from 1.2 V to 3.6 V, accepts 5 V–tolerant inputs/outputs, and supports mixed-voltage translation between 3.3 V and 5 V buses in high-speed memory or peripheral interfaces.

For engineers reviewing the 74LVC162245ADGVJ datasheet, 74LVC162245ADGVJ pinout, 74LVC162245ADGVJ application, or 74LVC162245ADGVJ equivalent, this device delivers deterministic bidirectional data flow control, IOFF partial power-down protection, Schmitt-trigger input noise immunity, and bus hold functionality (on LVCH variant), making it critical for robust board-level signal integrity in industrial and embedded systems.

Technical Context

This transceiver implements two independent 8-bit bidirectional data paths, each with dedicated DIR and OE pins enabling granular control over direction and output state. Its internal architecture includes Schmitt-trigger inputs for slow-edge tolerance and an IOFF circuit that disables outputs during power-down to prevent backflow current.

The device integrates 30 Ω series termination resistors on all I/O lines to dampen reflections on PCB traces, reducing signal overshoot and improving timing margins. Bus hold circuitry (on 74LVCH162245A variants) maintains stable logic states on unused data inputs without external pull-ups, simplifying system design in sparse-bus configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.2 V to 3.6 V - Enables operation across low-power IoT nodes and standard 3.3 V logic domains.
Input/Output Voltage Tolerance	Up to 5.5 V - Allows direct interfacing with legacy 5 V peripherals without level-shifting circuitry.
Propagation Delay (t_pd)	1.0 ns (min) to 8.5 ns (max) at V_CC = 3.3 V - Supports >100 MHz data rates in synchronous bus applications.
Termination Resistance	30 Ω series per I/O - Matches typical PCB trace impedance to suppress ringing and improve signal fidelity.
IOFF Leakage Current	±10 μA max at V_CC = 0 V - Ensures safe hot-swap and partial power-down behavior in modular systems.
Bus Hold Current (LVCH)	±75 μA at V_CC = 3.0 V - Maintains valid logic levels on floating data lines without external components.
ESD Protection	HBM >2000 V, CDM >1000 V - Meets industrial-grade robustness requirements for handling and assembly.

Pinout & Package

74LVC162245ADGVJ uses the SOT480-1 (TVSOP48) package: 48-pin plastic thin shrink small outline, 4.4 mm body width, 0.4 mm lead pitch. Pin numbering follows standard counter-clockwise layout starting from pin 1 (1DIR) at top-left corner.

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR	Direction control input	Active-HIGH logic selects data flow direction per 8-bit port (A→B or B→A).
1OE, 2OE	Output enable input (active LOW)	Drives corresponding 8-bit port into high-impedance state when HIGH; enables tristate isolation.
1A0–1A7, 2A0–2A7	Data I/O port A	First and second 8-bit bidirectional data bus segment connected to local controller side.
1B0–1B7, 2B0–2B7	Data I/O port B	First and second 8-bit bidirectional data bus segment connected to peripheral/memory side.
VCC (pins 7, 18, 31, 42)	Power supply	Four distributed supply pins minimize IR drop and improve noise immunity across wide bus.
GND (pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight ground pins reduce ground bounce and support clean return paths for all 16 I/Os.

Key Features

Feature	Design Value
Dual independent 8-bit control	Separate 1DIR/1OE and 2DIR/2OE allow asymmetric bus arbitration-e.g., one port transmitting while the other receives.
Integrated 30 Ω series termination	Eliminates need for 32 discrete 30 Ω resistors, saving PCB area and reducing BOM count in high-density designs.
IOFF partial power-down	Prevents damaging back-current when V_CC is off but I/O lines remain energized-critical for hot-pluggable modules.
Schmitt-trigger inputs	Accepts slow-rising/falling signals down to 10 ns/V transition rate, easing timing closure with RC-filtered or long-trace signals.
5 V tolerant I/O	Operates safely with 5 V signals while powered from 1.2–3.6 V, enabling seamless voltage translation without external translators.

Applications

Memory Interface

Industrial Backplane

Use Scenario: Bidirectional data transfer between a 3.3 V FPGA and legacy 5 V SRAM or Flash memory.

IC Role / Device Role / Timing Role: Level-translating transceiver managing address/data bus handshaking with controlled slew and termination.

Use Value: Eliminates discrete level shifters and termination networks while maintaining setup/hold timing under 5 V noise coupling.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVCH162245ADGV	Includes bus hold on all data inputs; identical pinout and electrical specs otherwise.	Preferred where unused data lines must be held without external resistors-e.g., configurable daughterboards.	Select when bus hold is required; otherwise 74LVC162245ADGV offers same core functionality at lower cost.
SN74LVC162245ADGGR	Texas Instruments variant; same 48-pin TVSOP package, but propagation delay up to 9.5 ns (vs. 8.5 ns max) and no IOFF spec.	Acceptable for non-hot-swap systems; lacks guaranteed power-down isolation for modular hardware.	Choose only if TI sourcing preference exists and partial power-down is not required.

Compared with 74LVCH162245ADGV, the 74LVC162245ADGVJ omits bus hold but retains identical timing, termination, and IOFF-making it optimal for fixed-configuration systems where BOM cost and simplicity outweigh hold functionality. Versus SN74LVC162245ADGGR, it provides tighter t_pd and certified IOFF, critical for industrial modularity.

FAQ

Does 74LVC162245ADGVJ support true 5 V operation?

No. The device operates from 1.2 V to 3.6 V supply but accepts 5 V–tolerant inputs and drives 5 V–compatible outputs. Its internal logic runs at V_CC; 5 V tolerance is achieved via clamping diodes and oxide-thickness design-not full 5 V rail operation. This enables safe interfacing with 5 V peripherals while minimizing dynamic power consumption.

Can 1DIR and 2DIR be tied together for unified 16-bit operation?

Yes. Connecting 1DIR and 2DIR allows simultaneous direction control across both 8-bit ports, converting the device into a single 16-bit transceiver. However, independent control remains possible-and often preferred-for asymmetric protocols like split-address/data buses or multi-master arbitration where ports require different timing or direction sequencing.

What is the impact of omitting external termination when using the integrated 30 Ω resistors?

The 30 Ω resistors are designed for source-series termination on CMOS drivers driving ~60 Ω transmission lines. Omitting additional external termination avoids double-termination, which would cause excessive signal attenuation. Use only the internal 30 Ω resistors unless trace impedance deviates significantly from 60 Ω-then adjust external matching accordingly.

How does IOFF behavior differ from standard 3-state disable?

Standard 3-state (via OE) disconnects outputs electrically but leaves internal circuitry powered; IOFF actively disables output drivers and isolates I/O pins even when V_CC = 0 V. This prevents current backflow from live buses into a powered-down subsystem-a requirement for hot-swap compliance and fault-tolerant modular designs.
