NXP Semiconductors 74LV241D,118

Overview

74LV241D,118 from NXP Semiconductors is an octal non-inverting 3-state buffer/line driver in SO20 package, operating from 1.0 V to 3.6 V supply, with propagation delay of 8 ns (typ) at VCC = 3.3 V and CL = 15 pF, input capacitance of 3.5 pF, and dual independent output-enable control (1OE active LOW, 2OE active HIGH). It serves as a bidirectional bus interface or data isolation element in low-voltage industrial control backplanes.

For engineers reviewing the 74LV241D,118 datasheet, 74LV241D,118 pinout, 74LV241D,118 application, or 74LV241D,118 equivalent, this device supports voltage-level translation between 1.2 V–3.6 V logic domains, delivers TTL-compatible inputs at VCC ≥ 2.7 V, and enables precise timing-critical bus arbitration via separate 1OE/2OE controls - critical for FPGA-to-ASIC interconnects and modular I/O expansion systems.

Technical Context

The 74LV241D,118 implements two independent 4-bit non-inverting buffer groups (1A0–1A3 → 1Y0–1Y3 and 2A0–2A3 → 2Y0–2Y3), each with dedicated 3-state enable: 1OE (pin 1, active LOW) and 2OE (pin 19, active HIGH). Its Si-gate CMOS process ensures rail-to-rail output swing and low ground bounce (VOLP < 0.8 V at 3.3 V).

It complies with IEC 60134 absolute maximum ratings, supports −40 °C to +125 °C ambient operation, and features ESD protection exceeding 2000 V HBM and 200 V MM. Dynamic power dissipation is calculated using CPD = 30 pF, enabling accurate µW-level estimation across mixed-frequency bus loads.

FAQ

What supply voltage range does the 74LV241D,118 support?

The 74LV241D,118 operates from 1.0 V to 3.6 V, enabling direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families. Static characteristics are guaranteed from 1.2 V to 3.6 V, and functionality is maintained down to 1.0 V with input levels referenced to GND or VCC. This makes the 74LV241D,118 suitable for ultra-low-power battery-operated systems and multi-rail industrial controllers.

How do the 1OE and 2OE pins differ in logic polarity?

The 74LV241D,118 features asymmetric enable logic: 1OE (pin 1) is active LOW, meaning outputs 1Y0–1Y3 enter high-impedance when 1OE = HIGH; 2OE (pin 19) is active HIGH, so outputs 2Y0–2Y3 go high-Z when 2OE = LOW. This dual-polarity design allows flexible bus arbitration - for example, holding one group active while releasing the other without external inverters. The 74LV241D,118 datasheet confirms this behavior in Table 4 (Function table).

Is the 74LV241D,118 pin-compatible with 74HC241 or 74HCT241?

Yes, the 74LV241D,118 is pin and function compatible with 74HC241 and 74HCT241 per its General Description. All three share identical SO20 pinout, input/output mapping, and 3-state enable architecture. However, the 74LV241D,118 supports lower VCC (down to 1.0 V) and exhibits faster propagation delay (8 ns typ vs. ~15 ns for HC/HCT at 5 V), making it a drop-in upgrade in existing 3.3 V designs - though voltage tolerance differences must be verified for 5 V systems.

What is the maximum output drive capability of the 74LV241D,118?

The 74LV241D,118 delivers ±8 mA output current at VCC = 3.0 V, with VOL ≤ 0.40 V and VOH ≥ 2.40 V under that load. At VCC = 2.7 V, it sustains ±8 mA with VOL ≤ 0.2 V and VOH ≥ 2.5 V. These values are confirmed in Table 7 (Static characteristics) of the datasheet. This drive strength supports reliable signaling into 50 pF loads typical of PCB traces and up to four CMOS inputs, making the 74LV241D,118 appropriate for medium-fanout bus applications.

Does the 74LV241D,118 require external decoupling capacitors?

Yes, the 74LV241D,118 requires local ceramic decoupling - typically 100 nF X7R between VCC (pin 20) and GND (pin 10) - placed within 5 mm of the SO20 package. This mitigates supply noise induced by simultaneous output switching, especially critical given its measured ground bounce (VOLP < 0.8 V at 3.3 V). The 74LV241D,118 datasheet recommends this practice in Section 11 (Dynamic characteristics) to maintain signal integrity in high-speed bus environments.
