Nexperia USA Inc. 74LV14PW,118

Overview

74LV14PW,118 from Nexperia is a low-voltage CMOS hex inverting Schmitt trigger IC with 14-pin TSSOP package, operating from 1.0 V to 5.5 V supply, delivering six independent hysteresis-input inverters for noise-immune signal conditioning in industrial and embedded timing circuits. It transforms slow-rising/falling inputs into clean digital outputs with VT+ = 1.60 V and VT− = 0.65 V at VCC = 3.0 V, and supports −40 °C to +125 °C ambient operation.

For engineers reviewing the 74LV14PW,118 datasheet, 74LV14PW,118 pinout, 74LV14PW,118 application, or 74LV14PW,118 equivalent, key selection criteria include input hysteresis voltage (VH = 0.95 V typical at VCC = 3.0 V), propagation delay (13 ns typical at VCC = 3.3 V, CL = 15 pF), output drive capability (±6 mA), wide supply range (1.0–5.5 V), and thermal grade (−40 °C to +125 °C).

Technical Context

The 74LV14PW,118 implements six independent Schmitt-trigger inverter stages using Si-gate CMOS technology, each featuring asymmetric input thresholds (VT+ > VT−) to provide noise margin against spurious switching. Its hysteresis behavior is defined by fixed VT+ and VT− values that scale with VCC, enabling robust edge detection across supply voltages from 1.2 V to 5.5 V.

It is functionally compatible with 74HC14 and 74HCT14 but optimized for low-voltage operation down to 1.0 V, with TTL-level input acceptance verified at VCC = 2.7 V to 3.6 V. The device exhibits low dynamic power dissipation (CPD = 15 pF) and meets JESD8-7/8-5/8C/36 compliance for multi-voltage system interfacing.

FAQ

Can the 74LV14PW,118 operate reliably at 1.2 V supply?

Yes. The 74LV14PW,118 is fully specified down to 1.0 V supply, with functional operation guaranteed at 1.2 V per Table 5. Static characteristics including VT+, VT−, VOH, and VOL are characterized at VCC = 1.2 V, and propagation delay remains within specification (80 ns max) across the full −40 °C to +125 °C range.

Is the exposed pad on the TSSOP14 package electrically connected?

No. Per section 6.1 of the datasheet, the exposed pad (terminal 1 index area) is not a supply pin and has no electrical or mechanical requirement to be soldered. If soldered, it must remain floating or be connected to VCC-never to GND-to avoid violating internal thermal design assumptions.

What is the maximum capacitive load the 74LV14PW,118 can drive without exceeding propagation delay specs?

The datasheet specifies tpd = 13 ns typical at CL = 15 pF and VCC = 3.3 V. At CL = 50 pF, tpd increases to ≤22 ns (Table 7). For designs requiring <15 ns delay, keep load capacitance ≤15 pF; for ≤22 ns, up to 50 pF is acceptable. Exceeding 50 pF degrades timing predictability and may increase ground bounce.

Does the 74LV14PW,118 support hot-swap or live-insertion?

No. The device lacks Ioff protection or power-off isolation. Applying input signals while VCC = 0 V violates absolute maximum ratings (VI must stay within −0.5 V to VCC + 0.5 V), risking latch-up or damage. Always power VCC before applying inputs, and use series resistors if hot-swap is unavoidable.
