Product details

Overview

74LVC16245AEVK from Nexperia is a 16-bit 3-state bus transceiver with dual direction control (1DIR/2DIR) and dual output enables (1OE/2OE), operating from 1.2 V to 3.6 V supply, tolerant to 5.5 V inputs, and specified for −40 °C to +125 °C. It supports bidirectional data flow across two independent 8-bit ports or as a unified 16-bit interface in mixed-voltage systems (e.g., 3.3 V MCU ↔ 5 V peripheral). Schmitt-trigger inputs improve noise immunity on slow-rising signals.

For engineers reviewing the 74LVC16245AEVK datasheet, 74LVC16245AEVK pinout, 74LVC16245AEVK application, or 74LVC16245AEVK equivalent, this page delivers verified functional architecture, TSSOP48/TVSOP48 package mapping, IOFF-enabled partial power-down behavior, bus-hold capability (LVCH variant), and real-world timing constraints for synchronous bus interfacing in industrial control backplanes and FPGA I/O expansion.

Technical Context

This device implements a dual-8-bit flow-through transceiver architecture with independent directional control per port and active-low 3-state enable logic. Each port features Schmitt-trigger inputs and IOFF circuitry that disables outputs during power-down to prevent backflow current.

It supports voltage translation between 1.2 V–3.6 V logic domains while accepting up to 5.5 V on inputs-enabling direct connection to legacy 5 V TTL buses without level shifters. The LVCH variant adds bus-hold on all data I/Os, eliminating external pull-ups for unused pins.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	1.2 V to 3.6 V - Enables operation across low-power microcontrollers and mixed-voltage SoC interfaces.
Input voltage tolerance	Up to 5.5 V - Allows safe interfacing with 5 V peripherals without external clamping or translation.
Propagation delay (t_pd)	1.0 ns (min) to 6.0 ns (max) at V_CC = 3.3 V - Supports high-speed parallel bus timing up to ~100 MHz with margin.
IOFF leakage current	±10 μA max at V_CC = 0 V - Ensures robust isolation during hot-swap or partial power-down sequences.
Bus hold current (LVCH)	±75 μA at V_CC = 3.0 V - Maintains stable logic state on floating data lines without external resistors.
ESD rating (HBM)	>2000 V - Meets JEDEC JS-001 Class 2 for handling robustness in manufacturing and field environments.
Operating temperature	−40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drives.

Pinout & Package

74LVC16245AEVK is available in TSSOP48 (SOT362-1, 6.1 mm body width) and TVSOP48 (SOT480-1, 4.4 mm body width, 0.4 mm pitch) packages. Both are 48-pin surface-mount devices with exposed thermal pad variants not applicable to this part.

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR	Direction control input	Active-HIGH signal selecting data flow direction per 8-bit port (A→B or B→A).
1OE, 2OE	Output enable input	Active-LOW control enabling/disabling 3-state outputs for each port independently.
1A0–1A7, 2A0–2A7	Data I/O port A	First and second 8-bit bidirectional data bus segment connected to controller-side logic.
1B0–1B7, 2B0–2B7	Data I/O port B	First and second 8-bit bidirectional data bus segment connected to peripheral-side logic.
V_CC	Power supply	Single 1.2–3.6 V supply rail; four dedicated pins minimize IR drop and ground bounce.
GND	Ground reference	Eight GND pins distributed across package for low-inductance return paths and EMI suppression.

Key Features

Feature	Design Value
Dual independent 8-bit ports	Enables flexible partitioning of 16-bit data paths-e.g., separate address/data lanes or isolated subsystem communication.
IOFF partial power-down	Prevents damaging back-current when V_CC is unpowered, critical for hot-plug PCIe carrier boards and modular PLC I/O cards.
Schmitt-trigger inputs	Accepts slow-rising signals (≤10 ns/V at 3.3 V) from mechanical switches or long traces without added hysteresis circuitry.
5.5 V tolerant inputs	Eliminates need for discrete level translators when interfacing with 5 V legacy sensors, displays, or memory controllers.
Bus-hold (74LVCH16245A)	Maintains last valid logic state on floating data lines-reduces BOM count and PCB space vs. external 10 kΩ pull-ups.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC16245ADGGR	TSSOP48 package only; no bus-hold; identical V_CC range and 5.5 V tolerance.	Lacks bus-hold-requires external pull-ups on unused I/Os in low-pin-count test fixtures.	Select when cost sensitivity outweighs board space savings from eliminated resistors.
74ALVC16245PW	Wider V_CC range (1.65–3.6 V); higher drive strength (−24/+24 mA); no IOFF.	No power-down isolation-unsuitable for hot-swap or partial-power systems.	Choose for higher-speed (>125 MHz) or higher-drive applications where full power is always present.

Compared with SN74LVC16245ADGGR, the 74LVC16245AEVK adds bus-hold and IOFF-critical for unpopulated I/O management and system-level power sequencing. Versus 74ALVC16245PW, it trades peak drive for safer partial-power operation and broader voltage flexibility down to 1.2 V.

FAQ

Is 74LVC16245AEVK pin-compatible with 74LVC16245ADGG?

Yes-74LVC16245AEVK shares identical TSSOP48 pinout and electrical characteristics with 74LVC16245ADGG. Both use SOT362-1 package, same 48-pin assignment, and match on V_CC, GND, DIR, OE, and I/O pin functions. No layout change is required for drop-in replacement in existing designs.

Does 74LVC16245AEVK support true 5 V operation?

No-it operates from 1.2 V to 3.6 V only, but its inputs tolerate up to 5.5 V. This allows safe connection to 5 V signal sources while powered from 3.3 V or lower, enabling voltage translation without external components. V_CC must remain within 1.2–3.6 V at all times.

What is the difference between 74LVC16245A and 74LVCH16245A?

The 'H' suffix denotes bus-hold circuitry on all data I/Os (1A0–1A7, 1B0–1B7, etc.), eliminating need for external pull-up/down resistors. Non-H versions lack this feature. Control inputs (DIR, OE) do not have bus-hold in either variant. Electrical specs and pinout are otherwise identical.

Can 74LVC16245AEVK be used in hot-swap applications?

Yes-its IOFF circuitry actively disables outputs when V_CC = 0 V, limiting back-current to ±10 μA maximum. This protects live backplanes during card insertion/removal. Combined with 2000 V HBM ESD rating and −40 °C to +125 °C qualification, it meets key requirements for hot-pluggable industrial modules.
