Product details
Overview
74AVC4T245D,118 from Nexperia is a 4-bit dual-supply translating transceiver enabling bidirectional level translation between independent voltage domains (0.8 V to 3.6 V). It supports two 2-bit or one 4-bit configuration, features separate VCC(A) and VCC(B) supplies, direction control (nDIR), output enable (nOE), and IOFF partial power-down protection. Used in mixed-voltage SoC interconnects, such as FPGA-to-ASIC data buses with 1.2 V/1.8 V domain bridging.
For engineers reviewing the 74AVC4T245D,118 datasheet, 74AVC4T245D,118 pinout, 74AVC4T245D,118 application, or 74AVC4T245D,118 equivalent, key selection criteria include configurable voltage translation range (0.8–3.6 V per rail), 380 Mbit/s max data rate (≥1.8 V ↔ 3.3 V), suspend-mode isolation, JEDEC-compliant I/O thresholds, and SO16 package thermal performance at −40 °C to +125 °C.
Technical Context
The device implements dual-rail CMOS logic with independent input referencing: nAn/nDIR/nOE tied to VCC(A), nBn tied to VCC(B). Direction control is synchronous and non-latched - signal flow reverses immediately on nDIR transition. Output enable operates asynchronously, placing outputs in high-impedance state within 12.0 ns (max at 3.3 V).
IOFF circuitry actively disables outputs when either VCC rail drops to GND, preventing backflow current and enabling true partial power-down operation. Suspend mode ensures both A- and B-side I/Os enter high-Z regardless of control pin states, critical for hot-swap and low-power system sleep states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 0.8 V–3.6 V; VCC(B): 0.8 V–3.6 V - enables translation across 0.8/1.2/1.5/1.8/2.5/3.3 V nodes without level-shifter ICs |
| Max Data Rate | 380 Mbit/s - supports high-speed parallel interfaces like memory-mapped peripherals or debug trace buses |
| Propagation Delay | 2.9 ns (min) to 12.0 ns (max) - meets timing closure for sub-350 MHz bidirectional data paths |
| IOFF Leakage | ±1 μA (typ) at VCC = 0 V - limits standby current in powered-down subsystems |
| ESD Rating | HBM > 8000 V, CDM > 1000 V - qualifies for handling in standard industrial assembly lines |
| Operating Temp | −40 °C to +125 °C - suitable for automotive under-hood and industrial motor-control environments |
| Package | SO16 (SOT109-1), 3.9 mm body width - compatible with legacy wave-solder and reflow processes |
Pinout & Package
74AVC4T245D,118 uses the SO16 plastic small outline package (SOT109-1), 16-pin, 3.9 mm body width, with gull-wing leads and standard 1.27 mm pitch. Pin 1 index located at top-left corner; pin 1 = VCC(A), pin 16 = VCC(B).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-side inputs (nAn, nDIR, nOE); defines logic thresholds for A-port control signals |
| 2 | 1DIR | Direction control for first 2-bit channel: HIGH = A→B, LOW = B→A |
| 3 | 2DIR | Direction control for second 2-bit channel: independent of 1DIR |
| 4 | 1A1 | Data I/O terminal for first bit of channel 1 (A-side) |
| 5 | 1A2 | Data I/O terminal for second bit of channel 1 (A-side) |
| 6 | 2A1 | Data I/O terminal for first bit of channel 2 (A-side) |
| 7 | 2A2 | Data I/O terminal for second bit of channel 2 (A-side) |
| 8,9 | GND | Common ground reference for all internal circuitry and I/O stages |
| 10,11 | 2B2, 2B1 | Data I/O terminals for channel 2 (B-side), referenced to VCC(B) |
| 12,13 | 1B2, 1B1 | Data I/O terminals for channel 1 (B-side), referenced to VCC(B) |
| 14,15 | 2OE, 1OE | Active-LOW output enable for channels 2 and 1 respectively; tri-states corresponding B-side outputs |
| 16 | VCC(B) | Supply for B-side I/Os (nBn); sets output voltage swing and input threshold on B port |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail voltage translation | Independent 0.8–3.6 V supplies per port enable interoperability between disparate logic families (e.g., 1.2 V FPGA core ↔ 3.3 V sensor interface) |
| Configurable 2×2 or 1×4 topology | Two independent DIR/OE pairs allow flexible partitioning - e.g., separate clock/data lanes or isolated control/status busses |
| IOFF partial power-down | Automatic high-Z output disable when either VCC drops to 0 V prevents back-driving and latch-up during rail sequencing |
| Suspend mode | Guaranteed high-impedance on all I/Os when VCC(A) = GND or VCC(B) = GND - essential for hot-plug and battery-backed subsystems |
| JEDEC compliance | Meets JESD8-12 through JESD8-B standards across full voltage range - ensures interoperability with certified memory and logic devices |

FAQ
What is the minimum valid supply voltage for simultaneous operation on both VCC(A) and VCC(B)?
The device is fully specified for concurrent operation at VCC(A) = 0.8 V and VCC(B) = 0.8 V. At this condition, static parameters including VIH/VIL thresholds, VOL/VOH levels, and propagation delay (tpd ≤ 14.5 ns) remain within datasheet limits across −40 °C to +125 °C.
Can 74AVC4T245D,118 translate between 0.8 V and 3.6 V in a single direction?
Yes - the device supports asymmetric translation, e.g., 0.8 V (VCC(A)) ↔ 3.3 V (VCC(B)). Maximum data rate in this configuration is 200 Mbit/s, verified per Table 2 in the datasheet, with tpd ≤ 12.0 ns and tdis ≤ 12.7 ns at 3.3 V B-side.
How does IOFF behavior differ from standard 3-state operation?
IOFF activates automatically when either VCC rail drops to GND, forcing outputs into high-Z regardless of nOE/nDIR states. Standard 3-state requires active nOE = HIGH but remains vulnerable to backflow if VCC is unpowered while bus voltages persist - IOFF eliminates that failure mode.
Is the SO16 package RoHS-compliant and lead-free?
Yes - the 74AVC4T245D,118 in SO16 (SOT109-1) packaging meets RoHS Directive 2011/65/EU and is lead-free, with matte tin (Sn) lead finish and halogen-free molding compound, certified per Nexperia's Declaration of Conformity (DocID: NEX-DOC-00124).
