Product details
Overview
74LVC1T45GS,132 from Nexperia is a single-bit, dual-supply bidirectional level-translating transceiver with 3-state outputs, enabling voltage translation between independent 1.2 V to 5.5 V domains (e.g., 1.8 V MCU ↔ 3.3 V peripheral). It features separate VCC(A) and VCC(B) pins, DIR-controlled directionality, IOFF-enabled partial power-down, and operates across –40 °C to +125 °C.
For engineers reviewing the 74LVC1T45GS,132 datasheet, 74LVC1T45GS,132 pinout, 74LVC1T45GS,132 application, or 74LVC1T45GS,132 equivalent, key selection criteria include bidirectional level-shifting capability, IOFF leakage control during suspend mode, bus hold functionality (in LVCH variant), maximum data rate per supply pair, and XSON6 (SOT1202) package compatibility with high-density PCB layouts.
Technical Context
The device implements a dual-rail CMOS transceiver architecture where A-port logic levels are referenced to VCC(A), B-port to VCC(B), and DIR to VCC(A). Direction control is synchronous: DIR = HIGH enables A→B transmission; DIR = LOW enables B→A transmission. Both ports enter high-impedance OFF-state when either VCC rail is at GND (suspend mode).
IOFF circuitry actively disables outputs during power-down, limiting backflow current to ±2 μA (–40 °C to +125 °C), while bus hold (on 74LVCH1T45 variant) maintains floating inputs at valid logic levels without external resistors. Propagation delays range from 0.5 ns (5.0 V → 5.0 V) to 48.6 ns (1.5 V → 1.5 V, –40 °C to +125 °C), with tPHZ/tPLZ specifying enable/disable timing critical for bus arbitration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCC(A)/VCC(B)) | 1.2 V to 5.5 V each - supports mixed-voltage interconnects (e.g., 1.2 V FPGA ↔ 5.0 V sensor) |
| Max Data Rate | 420 Mbps (3.3 V → 5.0 V) - enables high-speed interface bridging without protocol conversion |
| IOFF Leakage Current | ±2 μA max (–40 °C to +125 °C) - prevents damaging back-current when one domain is powered off |
| Propagation Delay (A→B) | 0.7 ns min / 48.6 ns max - defines worst-case timing margin for synchronous bus handshaking |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - drives standard CMOS loads with noise margin under heavy capacitive loading |
| ESD Protection | HBM > 4000 V, CDM > 1000 V - meets industrial IEC 61000-4-2 system-level robustness requirements |
| Operating Temperature | –40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT1202), 1.0 × 1.0 × 0.35 mm body, no leads, 6 terminals, wettable flank terminations for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply reference for A port and DIR input - sets logic thresholds and output swing for A-side signals |
| 2 | GND | Common ground return - required for signal integrity and ESD path continuity |
| 3 | A | Bidirectional data I/O referenced to VCC(A) - connects to low-voltage controller (e.g., ARM Cortex-M core) |
| 4 | B | Bidirectional data I/O referenced to VCC(B) - interfaces with higher-voltage peripheral (e.g., UART transceiver) |
| 5 | DIR | Direction control input (active-HIGH) referenced to VCC(A) - determines real-time data flow path (A↔B) |
| 6 | VCC(B) | Supply reference for B port - independently configurable to match target peripheral voltage domain |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) each support 1.2 V–5.5 V - eliminates need for external level-shifters in heterogeneous voltage systems |
| IOFF partial power-down | Enables safe hot-plug operation and reduces system standby power by blocking leakage paths when unpowered |
| Suspend mode | Automatic high-Z on both ports if either VCC drops to GND - prevents bus contention during power sequencing |
| Bus hold (74LVCH1T45 variant) | Active internal pull-up/down on A/B pins - removes external bias resistors and improves noise immunity on unterminated lines |
| JEDEC-compliant voltage standards | Meets JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), JESD8C (2.7–3.6 V), JESD36 (4.5–5.5 V) - ensures interoperability across logic families |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCUR | Single-channel, auto-direction sensing (no DIR pin); lower drive (±2 mA); 1.65–5.5 V range only | Best for push-pull buses with inherent direction signaling (e.g., I²C); unsuitable for DIR-controlled parallel buses | Select when eliminating control logic overhead is prioritized over drive strength and full voltage flexibility |
| SN74AVC1T45DBVR | Wider temp range (–40 °C to +125 °C); same pinout; higher max speed (500 Mbps at 3.3 V→5.0 V); IOFF supported | Drop-in replacement with improved timing margin for high-frequency DDR or PCIe sideband signals | Choose for new designs requiring extended speed headroom or TI-ecosystem design reuse |
Compared with TXS0101DCUR and SN74AVC1T45DBVR, the 74LVC1T45GS,132 offers superior voltage flexibility (1.2 V minimum), tighter IOFF leakage control (±2 μA vs ±10 μA), and deterministic DIR-based direction control-critical for time-critical parallel interfaces where auto-sensing latency is unacceptable.

FAQ
What is the minimum operating voltage for VCC(A) and VCC(B) simultaneously?
The 74LVC1T45GS,132 supports independent operation down to 1.2 V on both VCC(A) and VCC(B) rails, enabling use in ultra-low-power 1.2 V SoC domains. Operation below 1.2 V is not characterized or guaranteed per datasheet Section 9.
Does the 74LVC1T45GS,132 include bus hold circuitry?
No - bus hold is exclusive to the 74LVCH1T45 variant. The 74LVC1T45GS,132 lacks internal bus hold; external pull-up/pull-down resistors are required for unused A or B pins to prevent floating inputs and undefined logic states.
Can DIR be driven from a different voltage domain than VCC(A)?
No - DIR is strictly referenced to VCC(A) and must be driven within 0.2×VCC(A) (LOW) to 0.7×VCC(A) (HIGH) per datasheet Table 8. Driving DIR from VCC(B) or another rail violates input voltage limits and risks latch-up or functional failure.
What is the thermal resistance (RθJA) of the SOT1202 package?
The SOT1202 (XSON6) package has a typical RθJA of 220 K/W, derived from datasheet Section 8 derating curves: Ptot derates linearly at 3.3 mW/K above 74 °C ambient. This value assumes JEDEC-standard 2-layer board with 1 in² copper pour.
