Product details

Overview

74LV244PW,118 from Nexperia is an octal 3-state buffer/line driver with dual independent output-enable controls (1OE, 2OE), operating across 1.0 V–5.5 V supply range. It functions as two 4-bit buffers or one 8-bit buffer, supports TTL-level inputs at VCC = 2.7–3.6 V, and delivers low ground bounce (< 0.8 V) and undershoot control (> 2 V) at 3.3 V - used in bidirectional bus interfacing between microcontrollers and peripheral ICs in industrial control modules.

For engineers reviewing the 74LV244PW,118 datasheet, 74LV244PW,118 pinout, 74LV244PW,118 application, or 74LV244PW,118 equivalent, key selection criteria include wide-voltage operation (1.0–5.5 V), dual 4-bit enable architecture, -40 °C to +125 °C temperature rating, TSSOP20 package footprint, and verified 3-state leakage (< 10 μA) and propagation delay (9 ns typical at 3.3 V).

Technical Context

The 74LV244PW,118 implements CMOS logic with input clamp diodes enabling safe interface to voltages exceeding VCC via current-limiting resistors. Its dual OE structure allows independent control of two 4-bit output groups (1Y0–1Y3 and 2Y0–2Y3), supporting selective bus isolation without full device disable.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V), and meets HBM ESD > 2000 V and CDM > 1000 V per JS-001/JS-002. Static and dynamic parameters are fully specified over -40 °C to +125 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.0 V to 5.5 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters.
Propagation Delay (t_pd)	9 ns typical at VCC = 3.3 V, CL = 15 pF - ensures timing compatibility with 100+ MHz system buses in industrial I/O expansion.
3-State Leakage (IOZ)	< 10 μA at VCC = 3.6 V - guarantees minimal bus contention during high-impedance state in shared-data-path systems.
Output Drive Strength	±8 mA at VCC = 3.0 V (VOH/VOL), ±16 mA at VCC = 4.5 V - sufficient to drive 15 pF loads across PCB traces and multiple CMOS inputs.
Operating Temperature	-40 °C to +125 °C - qualified for under-hood automotive auxiliary modules and industrial motor drives with extended thermal margins.
Input Clamp Diodes	Integrated - permits safe connection of inputs to voltages up to VCC + 0.5 V using external current-limiting resistors.

Pinout & Package

TSSOP20 plastic thin shrink small outline package (SOT360-1), 20-pin, 4.4 mm body width, 0.65 mm lead pitch, 1.1 mm max height - optimized for high-density PCB layouts in space-constrained embedded controllers.

Pin/Terminal	Circuit Role	Design Meaning
1, 19	1OE, 2OE	Active-low output enables - independently gate Group 1 (pins 18,16,14,12) and Group 2 (pins 3,5,7,9) into high-impedance state.
2, 4, 6, 8	1A0–1A3	Group 1 data inputs - routed to outputs 1Y0–1Y3 when 1OE = LOW.
17, 15, 13, 11	2A0–2A3	Group 2 data inputs - routed to outputs 2Y0–2Y3 when 2OE = LOW.
18, 16, 14, 12	1Y0–1Y3	Group 1 buffered outputs - 3-state, driven by 1A0–1A3 when 1OE = LOW.
3, 5, 7, 9	2Y0–2Y3	Group 2 buffered outputs - 3-state, driven by 2A0–2A3 when 2OE = LOW.
10	GND	Ground reference - return path for all input/output currents and internal logic.
20	VCC	Power supply - supplies core logic and output drivers; decoupling capacitor required within 5 mm.

Key Features

Feature	Design Value
Wide-Voltage Operation	1.0 V–5.5 V supply range - eliminates need for separate voltage translators in mixed-supply systems (e.g., 1.8 V MCU ↔ 3.3 V sensor bus).
Dual Independent Output Enables	Separate 1OE and 2OE pins - enables partial bus isolation (e.g., hold peripheral A active while disabling peripheral B on same data lines).
TTL-Compatible Inputs	Valid at VCC = 2.7–3.6 V - allows direct connection to legacy 5 V TTL outputs without external pull-ups or level shifters.
Low Ground Bounce	VOLP < 0.8 V at VCC = 3.3 V - reduces noise coupling into analog sections and improves signal integrity in mixed-signal PCBs.
High ESD Robustness	HBM > 2000 V, CDM > 1000 V - enhances reliability in manual handling and field-deployed equipment with frequent connector insertion.

Applications

Industrial PLC I/O Expansion

Microcontroller Bus Isolation

Use Scenario: Expanding GPIO count of a Cortex-M4-based PLC controller to drive 8-channel digital output modules.

IC Role / Device Role / Timing Role: Bidirectional buffer isolating MCU address/data bus from opto-isolated output stage; enables hot-swap-safe enable/disable per channel group.

Use Value: Dual OE control allows real-time reconfiguration of I/O mapping without resetting the entire bus, reducing downtime during field maintenance.

Use Scenario: Interfacing an ARM-based SoC with multiple SPI peripherals sharing a common data bus.

IC Role / Device Role / Timing Role: 3-state line driver managing contention between master and slave devices; provides clean signal edge integrity at 25 MHz clock rates.

Use Value: 9 ns t_pd and < 10 μA IOZ ensure deterministic bus arbitration and eliminate ghost reads during peripheral switching.

Automotive Body Control Module

Test Equipment Signal Conditioning

Use Scenario: Level-shifting and buffering signals between a 1.2 V domain MCU and 5 V CAN transceiver power supply domain.

IC Role / Device Role / Timing Role: Voltage-tolerant buffer translating logic levels while maintaining timing alignment across domains; clamped inputs prevent latch-up during load-dump transients.

Use Value: Input clamp diodes + 1.0 V min VCC support allow direct connection to 5 V nodes with only series resistors - no external protection circuitry needed.

Use Scenario: Driving calibrated test signals from a 3.3 V FPGA DAC to multiple DUT inputs simultaneously.

IC Role / Device Role / Timing Role: Low-skew octal driver ensuring matched rise/fall times across all 8 channels; minimizes inter-channel skew in parallel stimulus generation.

Use Value: Matched t_PLH/t_PHL (≤ 14 ns variation at 3.3 V) guarantees sub-100 ps inter-output skew for precision timing validation.

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
SN74LVC244APWR	Wider VCC range (1.65–3.6 V); lower ICC (10 μA typ); no 1.0 V operation.	Not suitable for 1.2 V systems; better for battery-powered 3.3 V designs requiring ultra-low quiescent current.	Select if operating exclusively at 1.65–3.6 V and minimizing standby power is critical.
74AHC244PW,118	Faster t_pd (5.5 ns @ 5 V); higher VCC max (+6.0 V); no 1.0 V operation; no TTL input compatibility.	Better for high-speed 5 V systems but incompatible with sub-2 V logic or legacy TTL sources.	Select for 5 V industrial backplanes where speed > 100 MHz is required and voltage margin is ≥ 5.5 V.

Compared with SN74LVC244APWR and 74AHC244PW,118, the 74LV244PW,118 uniquely supports 1.0 V operation and TTL input compatibility - making it the only choice for mixed-voltage systems spanning 1.2 V to 5 V with legacy interface requirements.

FAQ

Can 74LV244PW,118 operate reliably at 1.2 V supply?

Yes. The 74LV244PW,118 is fully specified down to VCC = 1.0 V, with guaranteed functionality and DC characteristics from 1.2 V onward. At 1.2 V, VIH is 0.9 V min and VOL is 0.3 V max under 100 μA load - validated across -40 °C to +125 °C per datasheet Table 6.

What is the maximum capacitive load this device can drive?

The 74LV244PW,118 is characterized up to 50 pF load capacitance (Table 9), with t_pd = 12 ns max at VCC = 2.7 V and CL = 50 pF. For reliable 3.3 V operation, it drives 15 pF loads with 9 ns typical delay - sufficient for standard PCB traces and up to 3 downstream CMOS inputs.

Does this part support hot insertion or live bus connection?

Yes - integrated input clamp diodes allow safe connection to voltages up to VCC + 0.5 V when used with current-limiting resistors (Section 1, General Description). This enables controlled live insertion into powered buses, provided external resistors limit IIK to ≤ ±20 mA per datasheet Table 4.

How does the dual OE architecture improve system design?

Dual OE (1OE and 2OE) enables independent control of two 4-bit output groups - allowing selective bus partitioning. For example, one group can remain active while the other is tri-stated during memory-mapped peripheral access, eliminating bus contention without full system reset or additional glue logic.
