Product details
Overview
74LV27D,118 from NXP Semiconductors (formerly Philips) is a triple 3-input NOR gate in a 14-pin SO package, operating from 1.0 V to 5.5 V supply, with 8 ns typical propagation delay at 3.3 V/15 pF, 3.5 pF input capacitance, and standard-output drive capability. It serves as a logic-level combinatorial gate in low-voltage digital control circuits such as address decoding and enable signal generation.
For engineers reviewing the 74LV27D,118 datasheet, 74LV27D,118 pinout, 74LV27D,118 application, or 74LV27D,118 equivalent, key selection criteria include its wide VCC range (1.0–5.5 V), TTL-input compatibility at 2.7–3.6 V, ground bounce <0.8 V, VOH undershoot >2 V at 3.3 V, and pin/function compatibility with 74HC/HCT27.
Technical Context
The 74LV27D,118 implements three independent 3-input NOR functions using low-voltage Si-gate CMOS technology, with inputs tolerant of TTL logic levels when VCC is between 2.7 V and 3.6 V. Its output stage delivers standard drive strength-capable of sourcing/sinking ±25 mA per output under specified conditions.
It operates across –40 °C to +125 °C ambient temperature, supports dynamic power estimation via CPD = 24 pF per gate, and meets IEC 60134 absolute maximum ratings including VCC up to +7.0 V and storage temperature from –65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC 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 |
| tPHL/tPLH | 8 ns typical at VCC = 3.3 V, CL = 15 pF - ensures timing predictability in high-speed control paths |
| CI | 3.5 pF - minimizes capacitive loading on driving stages and reduces switching noise coupling |
| VOH / VOL | 2.82 V min / 0.40 V max at VCC = 3.0 V, IO = 6 mA - guarantees robust noise margins in 3.3 V systems |
| ICC (Quiescent) | 20 µA typical at VCC = 5.5 V - supports ultra-low static power in battery-backed or always-on logic |
| VIH/VIL | 2.0 V min / 0.8 V max at VCC = 2.7–3.6 V - ensures reliable recognition of TTL-level inputs without level shifters |
Pinout & Package
74LV27D,118 is housed in a 14-pin plastic small outline (SO) package per SOT108-1, 3.9 mm body width, rated for –40 °C to +125 °C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2, 4, 10 | 1B, 2B, 3B | Second input of each NOR gate - enables full 3-input combinatorial logic implementation |
| 5, 11, 13 | 1C, 2C, 3C | Third input of each NOR gate - provides complete 3-input NOR functionality per gate |
| 6, 8, 12 | 1Y, 2Y, 3Y | Active-low NOR outputs - drive downstream logic, LEDs, or enable lines with standard fanout |
| 7 | GND | Ground reference - must be low-impedance connection to minimize ground bounce effects |
| 14 | VCC | Positive supply - decoupling capacitor required near pin to suppress supply transients |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC27D,653 | Higher VCC min (2.0 V), slower tPHL/tPLH (15 ns typ @ 4.5 V), no TTL-input compatibility below 4.5 V | Requires ≥2.0 V supply; unsuitable for 1.2 V or 1.8 V domains where 74LV27D,118 operates | Select when higher noise immunity at 5 V is prioritized over low-voltage operation |
| SN74LVC27APW | Same VCC range (1.65–5.5 V), lower ICC (10 µA typ), but only rated to +85 °C (not +125 °C) | Limited to commercial/industrial temp range; not qualified for under-hood or extended-temperature industrial use | Select for cost-sensitive consumer or telecom applications where extended temperature is unnecessary |
Compared with 74HC27D,653 and SN74LVC27APW, the 74LV27D,118 uniquely supports operation down to 1.0 V while maintaining full –40 °C to +125 °C qualification and TTL-input compatibility at 3.3 V-making it the only option for ruggedized low-voltage control logic requiring both wide voltage headroom and extended temperature reliability.

FAQ
What is the minimum supply voltage at which 74LV27D,118 guarantees functional operation?
The 74LV27D,118 guarantees functional operation down to VCC = 1.0 V, with DC characteristics fully specified from VCC = 1.2 V to 5.5 V. At 1.0 V, inputs are recognized as HIGH or LOW when driven to GND or VCC respectively, though timing parameters are not guaranteed below 1.2 V per the datasheet's recommended operating conditions.
Is 74LV27D,118 pin and function compatible with 74HC27 or 74HCT27?
Yes, the 74LV27D,118 is explicitly stated in its Philips product data to be pin and function compatible with 74HC/HCT27. This includes identical pin configuration (14-pin SO), identical logic function (triple 3-input NOR), and matching truth table behavior-enabling drop-in replacement in existing 74HC27 designs when low-voltage operation is needed.
Does 74LV27D,118 support TTL-level inputs at 3.3 V supply?
Yes, the 74LV27D,118 accepts TTL input levels when VCC is between 2.7 V and 3.6 V. At VCC = 3.3 V, VIH is guaranteed ≥2.0 V and VIL ≤0.8 V, which aligns with standard TTL output specifications (VOH ≥2.4 V, VOL ≤0.4 V), allowing direct interfacing without level-shifting circuitry.
What is the maximum output current rating per pin for 74LV27D,118?
The 74LV27D,118 has a maximum DC output source or sink current rating of ±25 mA per output pin (1Y, 2Y, 3Y) under conditions where –0.5 V < VO < VCC + 0.5 V. This rating applies to standard-output configurations and is validated across the full –40 °C to +125 °C operating range.
Can 74LV27D,118 be used in applications requiring operation beyond +85 °C ambient?
Yes, the 74LV27D,118 is qualified for operation from –40 °C to +125 °C ambient temperature, as confirmed in the "Recommended Operating Conditions" table and "Ordering Information" section of the Philips product data. This makes it suitable for under-hood automotive, industrial motor drives, and other high-temperature environments where commercial-grade logic would fail.
