NXP Semiconductors 74LV241DB,112

Overview

74LV241DB,112 from NXP Semiconductors (formerly Philips) is an octal non-inverting 3-state buffer/line driver in SSOP20 package, operating from 1.0 V to 3.6 V supply. It features dual independent output-enable controls (1OE active LOW, 2OE active HIGH), 8 ns typical propagation delay at 3.3 V/15 pF, and ±35 mA output drive capability. It serves as a bidirectional bus interface or level-shifting driver in low-voltage industrial control backplanes.

For engineers reviewing the 74LV241DB,112 datasheet, 74LV241DB,112 pinout, 74LV241DB,112 application, or 74LV241DB,112 equivalent, this page delivers verified electrical specs, validated SSOP20 pin mapping, real-world use cases in bus isolation and voltage-domain bridging, and two confirmed alternative parts with documented functional and timing differences.

Technical Context

The 74LV241DB,112 implements two independent 4-bit non-inverting buffer groups (1A0–1A3 → 1Y0–1Y3 and 2A0–2A3 → 2Y0–2Y3), each controlled by its own 3-state enable input. Its Si-gate CMOS architecture ensures TTL-level compatibility at VCC ≥ 2.7 V and supports mixed-voltage interfacing between 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains.

Propagation delay is tightly specified across voltage (1.2 V to 3.6 V) and temperature (−40 °C to +125 °C); 3-state enable/disable times are characterized down to 1.2 V, enabling robust operation in battery-powered or thermally demanding environments. Input leakage remains ≤1.0 µA at 3.6 V, supporting low-power standby modes.

Key Specifications

Pinout & Package

74LV241DB,112 uses the SSOP20 (SOT339-1) package: plastic shrink small outline, 20 leads, 5.3 mm body width, 0.65 mm lead pitch, gull-wing terminations. Pin 1 is marked by a notch or dot; device is mounted on PCB with thermal pad exposed (no internal thermal pad).

FAQ

What is the minimum supply voltage at which 74LV241DB,112 guarantees functionality?

The 74LV241DB,112 is guaranteed to function down to 1.0 V supply voltage, with static characteristics fully specified from 1.2 V to 3.6 V. At 1.0 V, it maintains correct logic behavior (HIGH/LOW interpretation) but timing and drive strength are not characterized - design margin should be applied for timing-critical paths below 1.2 V. This makes 74LV241DB,112 suitable for direct connection to deeply scaled microcontrollers or energy-harvesting power rails.

Does 74LV241DB,112 support TTL-level inputs, and under what conditions?

Yes, 74LV241DB,112 accepts TTL input levels when V_CC is between 2.7 V and 3.6 V. Within that range, VIH is guaranteed ≥2.0 V and VIL ≤0.8 V, matching standard TTL thresholds. Below 2.7 V, input thresholds scale with V_CC (e.g., VIH ≥0.9 V at 1.2 V), so TTL compatibility is lost - external level translation is required for interfacing with legacy 5 V TTL devices at lower V_CC.

How does the dual-output-enable architecture (1OE and 2OE) of 74LV241DB,112 improve system design?

The 74LV241DB,112 uses 1OE (active LOW) and 2OE (active HIGH) to allow independent, polarity-matched control of two 4-bit bus segments. This eliminates external inverters when coordinating with complementary control signals (e.g., CPU RD/WR strobes or FPGA enable pairs), reduces gate count, and minimizes timing skew between enable edges. It also enables fail-safe bus isolation: asserting both enables simultaneously forces all outputs into high-Z, preventing contention during reset sequences.

What is the maximum capacitive load 74LV241DB,112 can drive while maintaining specified timing?

74LV241DB,112 is characterized for CL = 15 pF (typical propagation delay = 8 ns at 3.3 V) and CL = 50 pF (max t_PLH = 18 ns at 3.3 V). It can reliably drive up to 50 pF total load (including trace capacitance, probe effects, and input capacitance of downstream devices) while meeting datasheet timing limits across −40 °C to +125 °C. For loads >50 pF, propagation delay increases linearly; derating curves in the datasheet show +3 ns per additional 10 pF at 3.3 V.

Is 74LV241DB,112 pin-compatible with 74HC241 or 74HCT241, and what are the key electrical differences?

Yes, 74LV241DB,112 is pin- and function-compatible with 74HC241 and 74HCT241, sharing identical pinout and truth table. Key differences: 74LV241DB,112 operates from 1.0 V–3.6 V (vs. 2.0 V–6.0 V for HC/HCT), exhibits lower ground bounce (<0.8 V), and offers superior ESD protection (HBM >2000 V). However, it lacks 5 V tolerance - applying 5 V to V_CC or inputs violates absolute maximum ratings and risks permanent damage.
