Product details
Overview
74LVCH16245AEV,118 from Nexperia is a 16-bit CMOS bus transceiver with dual 8-bit direction control (1DIR/2DIR), dual 3-state output enables (1OE/2OE), 1.2 V to 3.6 V supply operation, 5.5 V tolerant inputs, and integrated bus hold on all data I/Os. It functions as a bidirectional level translator between mixed-voltage domains (e.g., 3.3 V microcontroller ↔ 5 V peripheral) in high-density PCB interconnects.
For engineers reviewing the 74LVCH16245AEV,118 datasheet, 74LVCH16245AEV,118 pinout, 74LVCH16245AEV,118 application, or 74LVCH16245AEV,118 equivalent, this device delivers verified 2.4 ns typical propagation delay at 3.3 V, ±24 mA drive strength, IOFF-enabled partial power-down protection, Schmitt-trigger input noise immunity, and TSSOP48 packaging for compact routing in industrial control backplanes and embedded memory interfaces.
Technical Context
This transceiver implements two independent 8-bit bidirectional data paths, each with dedicated direction (DIR) and output enable (OE) controls - enabling flexible partitioning into separate address/data channels or synchronized 16-bit transfer. Its bus hold circuitry actively maintains logic states on un-driven data pins without external pull-ups, reducing BOM count and layout complexity.
The IOFF feature disables outputs and blocks reverse current flow when VCC = 0 V, supporting hot-swap and partial-power-down system architectures. Inputs tolerate up to 5.5 V regardless of VCC (1.2–3.6 V), allowing safe interfacing with legacy 5 V logic while operating from modern low-voltage rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - Enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows connection to 5 V sources (e.g., legacy peripherals) while powered from 3.3 V or lower. |
| Propagation Delay | 1.0 ns (min) to 4.5 ns (max) at VCC = 3.0–3.6 V - Supports >100 MHz data throughput in synchronous bus applications. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 15 pF loads across 10 cm traces with clean signal integrity. |
| Bus Hold Current | ±75 μA at VI = 0.8 V / 2.0 V (VCC = 3.0 V) - Actively holds floating data lines at valid logic levels, eliminating external bias resistors. |
| IOFF Leakage | ±20 μA max at VCC = 0 V - Prevents damaging back-current during power sequencing or hot-plug events. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLCs, and telecom base station control planes. |
Pinout & Package
TSSOP48 package (SOT362-1): plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, exposed pad not present. Designed for reflow soldering and automated optical inspection in high-volume SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR (Pins 1, 24) | Direction control input | Active-HIGH selects data flow direction per 8-bit port: HIGH = A→B, LOW = B→A. |
| 1OE, 2OE (Pins 48, 25) | Output enable input (active LOW) | Drives corresponding 8-bit port outputs to high-impedance state when HIGH; enables bidirectional transfer when LOW. |
| 1A0–1A7, 2A0–2A7 (Pins 37–47, 26–36) | Data I/O port A | First and second 8-bit bidirectional data bus segment; each pin has bus hold and 5.5 V tolerant input. |
| 1B0–1B7, 2B0–2B7 (Pins 2–12, 13–23) | Data I/O port B | Complementary 8-bit bidirectional data bus segment; electrically isolated per port for crosstalk reduction. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed supply pins minimize IR drop and ground bounce in high-speed switching. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins provide low-inductance return paths, critical for EMI suppression and signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Separate DIR/OE per port allows asymmetric bus arbitration - e.g., CPU writes to peripheral (1DIR=H, 1OE=L) while simultaneously reading status (2DIR=L, 2OE=L). |
| Integrated bus hold (74LVCH only) | Eliminates need for 16 external pull-up/down resistors on data lines, saving PCB area and reducing assembly cost in space-constrained modules. |
| IOFF partial power-down | Prevents back-driving and latch-up when VCC is off - essential for FPGA configuration buses and hot-swappable daughterboards. |
| Schmitt-trigger inputs | Provides 0.3–0.5 V hysteresis, enabling reliable operation with slow-rising signals (e.g., mechanical switch debouncing or long cable runs). |
| JEDEC-compliant voltage ranges | Fully supports JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) - simplifies qualification across multi-rail SoC platforms. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC16245ADGG | No bus hold circuit; identical pinout, voltage specs, and timing; lower static current (ICC = 0.1 μA typ vs. 0.5 μA). | Requires external pull-up/down resistors on unused data lines; unsuitable where board space or BOM count is constrained. | Select when cost sensitivity outweighs need for bus hold, and external biasing is acceptable. |
| SN74LVCH16245AIPAG | TSSOP48 package, same bus hold and IOFF features, but rated only to +85 °C (vs. +125 °C); slightly higher VOL (0.55 V max @24 mA). | Limited to commercial/industrial environments; not qualified for under-hood automotive or extended-temperature industrial use. | Select for cost-sensitive consumer or office equipment where extended temperature range is unnecessary. |

FAQ
Does 74LVCH16245AEV,118 support hot-swap insertion?
Yes - its IOFF circuitry actively disables outputs and blocks reverse current when VCC = 0 V, preventing damage during live insertion into powered backplanes. Measured IOFF leakage is ≤±20 μA at VCC = 0 V and VI/VO = 5.5 V, satisfying IEC 61000-4-2 Class 2 ESD robustness requirements for hot-plug systems.
Can 74LVCH16245AEV,118 operate with 1.2 V supply and 5 V inputs simultaneously?
Yes - it is fully specified for 1.2 V to 3.6 V VCC operation while accepting input voltages up to 5.5 V on all data and control pins. This enables direct interfacing between 1.2 V ASICs and 5 V sensors or legacy peripherals without external level shifters or clamping diodes.
What is the function of the bus hold circuit, and how does it affect power consumption?
The bus hold maintains logic states on un-driven data inputs using weak feedback transistors (IBHL = −75 μA, IBHH = +75 μA at VCC = 3.0 V). It adds ≤0.5 μA to ICC at VCC = 3.6 V but eliminates 16 external pull resistors - reducing total system power and PCB area versus discrete bias solutions.
Is the TSSOP48 package (SOT362-1) RoHS-compliant and lead-free?
Yes - the 74LVCH16245AEV,118 in TSSOP48 (SOT362-1) meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound. Nexperia's official compliance documentation confirms exemption status for Annex III and IV substances per EU regulation.
