NXP Semiconductors 74LVC27PW,118

Overview

74LVC27PW,118 from NXP Semiconductors is a triple 3-input NOR gate logic IC in TSSOP14 package, operating from 1.2 V to 3.6 V supply, with 5.5 V-tolerant inputs and guaranteed operation from −40 °C to +125 °C. It delivers sub-6 ns propagation delay at 3.3 V and supports direct TTL-level interfacing in low-power digital control circuits.

For engineers reviewing the 74LVC27PW,118 datasheet, 74LVC27PW,118 pinout, 74LVC27PW,118 application, or 74LVC27PW,118 equivalent, this page provides verified functional identity, validated pin mapping for TSSOP14, confirmed static/dynamic specifications across voltage/temperature ranges, and two rigorously cross-referenced alternative parts for logic-level compatibility assessment.

Technical Context

The 74LVC27PW,118 implements three independent 3-input NOR gates using advanced CMOS technology, enabling discrete logic synthesis without external pull-ups or level shifters. Its input structure accepts voltages up to 5.5 V regardless of VCC, allowing mixed-voltage system interfacing.

It complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), and meets stringent ESD requirements: HBM >2000 V, MM >200 V, CDM >1000 V - ensuring robustness in automated assembly and field operation.

FAQ

What is the maximum input voltage the 74LVC27PW,118 can tolerate?

The 74LVC27PW,118 accepts input voltages up to 5.5 V regardless of VCC level - a key feature enabling direct interface with 5 V logic families without external level shifters. This tolerance is explicitly specified in Table 4 (Limiting Values) and confirmed across all operating conditions in the NXP datasheet Rev. 6.

Does the 74LVC27PW,118 support operation at 1.2 V supply?

Yes, the 74LVC27PW,118 is fully specified down to 1.2 V VCC, as stated in Table 5 (Recommended Operating Conditions). At 1.2 V, it maintains functional operation with VIH = 1.08 V and VOL ≤ 0.12 V, though propagation delay increases to 11.6 ns (max) at −40 °C to +85 °C.

What is the operating temperature range for the 74LVC27PW,118?

The 74LVC27PW,118 is rated for −40 °C to +125 °C ambient operation, as confirmed in Table 1 (Ordering Information) and Table 5. This extended grade applies specifically to the TSSOP14 (SOT402-1) package variant and is validated per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life tests.

Is the 74LVC27PW,118 pin-compatible with other 74LVC27 package variants?

Yes - the 74LVC27PW,118 (TSSOP14) shares identical pin numbering and function mapping with SO14 (74LVC27D), SSOP14 (74LVC27DB), and DHVQFN14 (74LVC27BQ) variants, as shown in Figure 4 and Table 2 of the datasheet. All variants use the same 14-pin assignment: inputs on pins 1/2/13, 3/4/5, 9/10/11; outputs on 12/6/8; GND on 7; VCC on 14.

What logic state does the 74LVC27PW,118 output when all three inputs are LOW?

When all three inputs (e.g., 1A, 1B, 1C) are LOW, the corresponding output (1Y) goes HIGH - consistent with NOR gate truth table behavior. This is explicitly defined in Table 3 (Function Selection), where "L L L → H" is the only condition yielding HIGH output; all other combinations produce LOW.
