Product details
Overview
74LVC2245AD,118 from Nexperia is an octal 3-state transceiver with integrated 30 Ω series termination resistors, bidirectional data flow controlled by DIR and OE pins, 1.2 V to 3.6 V supply operation, 5.5 V tolerant inputs, and -40 °C to +125 °C temperature range - used in high-speed bus interface applications between mixed-voltage domains (e.g., 3.3 V microcontroller to 5 V peripheral).
For engineers reviewing the 74LVC2245AD,118 datasheet, 74LVC2245AD,118 pinout, 74LVC2245AD,118 application, or 74LVC2245AD,118 equivalent, key selection considerations include direction-controlled bidirectional buffering, on-die 30 Ω series termination for signal integrity, IOFF-enabled partial power-down capability, and Schmitt-trigger inputs for noise immunity in noisy industrial bus environments.
Technical Context
This device implements a dual-bus transceiver architecture with independent send/receive (DIR) and output enable (OE) control logic. Its IOFF circuitry actively disables outputs during power-down, blocking backflow current when VCC = 0 V while inputs/outputs remain at up to 5.5 V.
It features Schmitt-trigger inputs for robust handling of slow-rising signals and supports JEDEC-compliant voltage interfaces across three operating ranges (1.65–1.95 V, 2.3–2.7 V, 2.7–3.6 V), enabling interoperability with legacy TTL and modern low-voltage logic families without external level-shifting components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 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 systems |
| Input Voltage Tolerance | Up to 5.5 V - allows safe connection to 5 V buses without external clamping diodes |
| Propagation Delay (tpd) | 1.5 ns (min) to 8.0 ns (max) at VCC = 3.0–3.6 V - supports >100 MHz bus timing with tight skew control |
| Output Termination | Integrated 30 Ω series resistors - reduces signal reflections on PCB traces without discrete components |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V, VI/VO = 5.5 V - prevents damaging back-current during hot-swap or partial power-down |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial control cabinets |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 3 for system-level robustness |

| 10 (GND) | Ground reference | 0 V return path for all internal logic and I/O circuits |
| 11–18 (B0–B7) | Port B data I/O | 8-bit bidirectional data port, electrically identical to Port A |
| 19 (OE) | Output enable (active LOW) | Drives both ports into high-impedance state when HIGH; synchronizes bus release |

Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω series termination | Eliminates need for eight external 30 Ω resistors, reducing BOM count and PCB area in DDR, address/data bus designs |

| Schmitt-trigger inputs | Provides 0.5 V typical hysteresis, rejecting noise spikes <1.5 ns wide on slow-rising control or status lines |
| 5.5 V tolerant I/O | Allows direct connection to 5 V legacy peripherals without level translators - simplifies mixed-voltage system integration |
| JEDEC-compliant voltage ranges | Validated operation across JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) standards |

FAQ
What is the maximum data rate supported by 74LVC2245AD,118?
The device supports reliable operation up to 100 MHz bus frequency, validated by propagation delay (tpd ≤ 8.0 ns at VCC = 3.0–3.6 V) and output skew (tsk(o) ≤ 1.5 ns). Signal integrity depends on trace length and termination; with on-die 30 Ω resistors, clean edges are maintained on 10 cm FR-4 traces at 25 MHz, and up to 50 MHz with proper layout.
Can 74LVC2245AD,118 be used with a 1.2 V supply?
Yes - it is fully specified from 1.2 V to 3.6 V. At 1.2 V, VIH is guaranteed ≥1.08 V and VOL ≤ 0.12 V with 100 μA load, enabling direct interface with 1.2 V ASICs and ultra-low-power MCUs. Propagation delay increases to 26 ns (typical), suitable for sub-40 MHz control buses.
How does the IOFF feature protect the device during power sequencing?
When VCC = 0 V, the IOFF circuit disables all outputs and isolates input/output terminals, limiting leakage current to ±10 μA even with 5.5 V applied to any pin. This prevents reverse current flow that could damage upstream drivers or cause latch-up in partially powered systems - verified per JESD78 Class II latch-up testing.
Is the SO20 package RoHS-compliant and lead-free?
Yes - the 74LVC2245AD,118 in SO20 (SOT163-1) package is lead-free and RoHS-compliant per Directive 2011/65/EU, with matte tin lead finish and halogen-free molding compound. It meets JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1), allowing unlimited floor life at ≤30 °C/60% RH.
