Product details

Overview

74LVC2244APW,112 from Nexperia is an octal 3-state buffer/line driver with dual independent output enables (1OE, 2OE), integrated 30 Ω series termination resistors on all eight outputs, 5 V tolerant I/O (up to 5.5 V), and operation from 1.2 V to 3.6 V supply. It supports mixed-voltage translation between 3.3 V and 5 V systems and features Schmitt-trigger inputs for noise immunity in slow-edge environments.

For engineers reviewing the 74LVC2244APW,112 datasheet, 74LVC2244APW,112 pinout, 74LVC2244APW,112 application, or 74LVC2244APW,112 equivalent, key selection criteria include 30 Ω on-die series termination for signal integrity, IOFF partial power-down protection, -40 °C to +125 °C industrial temperature range, and TSSOP20 package compatibility with high-density PCB layouts.

Technical Context

The device implements two independent 4-bit buffered paths, each controlled by its own active-low output enable (1OE for outputs 1Y0–1Y3; 2OE for 2Y0–2Y3). All inputs feature Schmitt-trigger action, enabling robust operation with slow-rising/falling signals and eliminating external hysteresis components.

IOFF circuitry actively disables outputs during power-down, blocking backflow current when VCC = 0 V and input/output voltages reach up to 5.5 V - critical for hot-swap and partial-power-down system architectures. The 30 Ω series termination is monolithically integrated per output, reducing BOM count and layout area versus discrete resistor solutions.

Use Scenario: Driving 8-bit parallel address/data bus between 3.3 V microcontroller and 5 V legacy I/O expansion cards in programmable logic controllers.

IC Role / Device Role / Timing Role: Bidirectional voltage translator and line driver with 30 Ω termination to suppress reflections on 10 cm traces routed across backplane connectors.

Use Value: Eliminates eight discrete 33 Ω resistors and associated layout space; IOFF prevents latch-up during card hot-swap events.

Test Equipment Digital Pattern Generator

Medical Diagnostic Imaging Data Link

Use Scenario: Driving calibrated 50 Ω coaxial cables from FPGA-based pattern generators in automated test equipment requiring precise edge control.

Use Value: Achieves <5 % overshoot on 100 MHz square waves into 50 Ω loads - eliminates need for external termination networks and improves repeatability.

Use Scenario: Buffering parallel pixel data streams from image sensor array to ADC interface in portable ultrasound devices operating from single-cell Li-ion (2.8–4.2 V).

IC Role / Device Role / Timing Role: Low-power (ICC < 10 μA typical) octal driver with 1.2 V minimum supply support - extends battery life while maintaining 5 V-tolerant sensor interface.

Use Value: Enables direct connection to 5 V analog front-end sensors without LDOs or charge pumps; CMOS low-power consumption reduces thermal load in sealed enclosures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC8T245RHLR	8-bit dual-supply translator (VCCA = 1.65–3.6 V, VCCB = 1.65–5.5 V); no integrated termination; higher ICC (20 μA typ)	Required when bidirectional level translation is needed; unsuitable where unidirectional 30 Ω termination is mandatory	Select only if system requires automatic direction control or true bidirectional data flow - not a drop-in replacement
74LVC244APW,118	Same pinout and function but lacks 30 Ω series termination; identical IOFF, Schmitt-trigger, and voltage tolerance specs	Used where external termination is preferred or board layout allows discrete resistors; lower cost but increases BOM and layout complexity	Choose when termination must be placed off-die for tuning or when cost sensitivity outweighs layout density benefits

Compared with SN74LVC8T245RHLR and 74LVC244APW,118, the 74LVC2244APW,112 uniquely integrates 30 Ω series termination per output - reducing signal integrity risk in high-speed parallel interfaces without increasing component count or layout area.

FAQ

What is the maximum allowed input voltage when VCC = 0 V?

The 74LVC2244APW,112 supports up to 5.5 V on any input or output pin even when VCC = 0 V, thanks to its IOFF circuitry. This capability is verified per JEDEC JS-002 CDM testing and enables safe hot-plug operation in modular systems where backplane signals may be present before local power is applied.

Can this device drive 50 Ω transmission lines directly?

Yes - the integrated 30 Ω series termination, combined with typical PCB trace impedance (~50–75 Ω), provides effective source termination for point-to-point connections. When driving a 50 Ω load, the total series impedance (30 Ω + driver output impedance ≈ 10 Ω) yields ~40 Ω source impedance, minimizing reflections for rise times >1 ns. For strict 50 Ω matching, add a 20 Ω external resistor in series.

How does the Schmitt-trigger input improve noise immunity?

The Schmitt-trigger inputs provide ≥0.3 V hysteresis at VCC = 3.3 V, meaning the rising threshold (VIH) is ~0.3 V higher than the falling threshold (VIL). This prevents multiple output transitions when input signals cross the logic threshold slowly or with noise - critical for long traces in industrial environments with EMI from motors or relays.

Is the TSSOP20 package RoHS and REACH compliant?

Yes - the 74LVC2244APW,112 in SOT360-1 (TSSOP20) packaging complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia confirms lead-free terminations, halogen-free molding compound, and full substance declarations available upon request through official channels.
