Product details

Overview

74LVT14DB,118 from Nexperia is a 3.3 V hex inverter with Schmitt-trigger inputs, bus-hold functionality, and IOFF partial power-down support. It provides six independent inverting channels, operates from 2.7 V to 3.6 V, tolerates 5.5 V inputs, and delivers ±20 mA/±32 mA output drive. It is used in noise-prone digital interface conditioning, such as legacy TTL-to-LVTTL level translation in industrial control backplanes.

For engineers reviewing the 74LVT14DB,118 datasheet, 74LVT14DB,118 pinout, 74LVT14DB,118 application, or 74LVT14DB,118 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.4–0.6 V), IOFF leakage (<±100 µA at VCC = 0 V), propagation delay (3.2–5.7 ns at 3.3 V), bus-hold input retention, and SO14 package compatibility with legacy PCB footprints.

Technical Context

The 74LVT14DB,118 implements six independent BiCMOS inverter stages, each with asymmetric Schmitt-trigger thresholds (VT+ = 1.5–2.0 V, VT− = 0.9–1.3 V) enabling robust noise immunity on slow-rising signals. Its bus-hold circuitry actively maintains last-valid logic state on unconnected inputs without external pull-ups.

IOFF logic disables outputs during power-down, blocking reverse current flow when VCC = 0 V while inputs or outputs remain biased up to 4.5 V. The device complies with JEDEC JESD8C (2.7–3.6 V) and supports operation across −40 °C to +85 °C with latch-up immunity >500 mA per JESD78 Class II Level A.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	2.7 V to 3.6 V - ensures compatibility with 3.3 V systems and margin for rail tolerance
Input voltage tolerance	Up to 5.5 V - allows direct interfacing with 5 V TTL buses without level shifters
Output drive	+32 mA / −20 mA - sufficient to drive multiple LVTTL loads or terminate stubs on medium-length traces
Propagation delay	3.2 ns (tPHL) / 3.8 ns (tPLH) at 3.3 V - enables reliable operation in ≤100 MHz clock distribution paths
Hysteresis voltage	0.4–0.6 V - rejects noise spikes ≤600 mV on input lines in electrically noisy environments
IOFF leakage	<±100 µA at VCC = 0 V - prevents backfeed current into powered-down sections of mixed-voltage boards
Operating temperature	−40 °C to +85 °C - qualified for industrial ambient conditions without derating

Pinout & Package

74LVT14DB,118 is supplied in SO14 (SOT108-1) package: plastic small outline, 14-lead, 3.9 mm body width, 1.27 mm lead pitch. Pin 1 is index-marked; leads are gull-wing, surface-mount compatible.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (1A–6A)	Schmitt-triggered data inputs with bus-hold; retain last logic state when floating
2, 4, 6, 8, 10, 12	Output (1Y–6Y)	Inverted outputs with ±20 mA/±32 mA drive; IOFF active when VCC = 0 V
7	GND	Reference ground for all I/O and internal circuitry; must be low-impedance connection
14	VCC	3.3 V supply input; powers internal BiCMOS logic and IOFF control circuitry

Key Features

Feature	Design Value
Schmitt-trigger inputs	Asymmetric thresholds (VT+ ≈ 1.7 V, VT− ≈ 1.1 V) provide 600 mV hysteresis for noise rejection on slow edges
Bus-hold circuitry	Eliminates need for external pull-up/pull-down resistors on unused inputs, reducing BOM count and board space
IOFF partial power-down	Outputs go high-impedance when VCC = 0 V, preventing back-current from live buses into unpowered IC sections
5.5 V tolerant inputs	Enables direct connection to 5 V TTL signal sources without external clamping or translation components
Latch-up immunity	Exceeds 500 mA per JESD78 Class II Level A - ensures robustness against transient overcurrent events

Applications

Industrial Backplane Interface

Legacy System Signal Conditioning

Use Scenario: Interfacing microcontroller GPIOs to legacy 5 V TTL peripheral cards in programmable logic controllers.

IC Role / Device Role / Timing Role: Level-translating inverter with noise filtering; converts 3.3 V MCU outputs to 5 V-compatible signals while rejecting EMI on long backplane traces.

Use Value: Eliminates discrete level shifters and pull-up networks, reducing component count by ≥3 per channel and improving signal integrity via hysteresis.

Use Scenario: Buffering and cleaning reset or enable signals in aging test equipment where input edges are slow and noisy.

IC Role / Device Role / Timing Role: Schmitt-trigger inverter providing clean, fast-edged outputs from degraded input waveforms with rise/fall times >100 ns.

Use Value: Prevents metastability in downstream logic by ensuring monotonic transitions; bus-hold retains valid state during hot-swap events.

Power Sequencing Control

Multi-Voltage Board Isolation

Use Scenario: Generating synchronized power-good or reset signals across subsystems with staggered power-up sequences.

IC Role / Device Role / Timing Role: Inverting buffer with IOFF; isolates powered-down domains while allowing shared control lines to remain active.

Use Value: Enables safe partial power-down without risk of backfeed current damaging unpowered rails or violating I/O voltage limits.

Use Scenario: Isolating 3.3 V FPGA configuration I/O from 5 V sensor interface circuits on shared PCBs.

IC Role / Device Role / Timing Role: Voltage-tolerant inverter acting as bidirectional signal conditioner between non-matching voltage domains.

Use Value: Avoids dedicated level translators; 5.5 V input tolerance and 3.3 V output swing meet both domain requirements with single device.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex inverter with Schmitt-trigger applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC14APWR	Lower VCC range (1.65–3.6 V); no IOFF; 5 V tolerant but no bus-hold	Requires external pull-ups on unused inputs; unsuitable for partial power-down architectures	Select when cost sensitivity outweighs IOFF and bus-hold needs; verify input biasing in unpopulated configurations
74LVTH14PW,118	Higher drive (+64 mA/−64 mA); same SO14 footprint; includes bus-hold and IOFF but wider VCC (2.7–3.6 V)	Delivers higher current for driving capacitive loads or longer traces; identical thermal and pinout compatibility	Choose for demanding signal integrity cases where tPLH/tPHL < 3 ns and load capacitance exceeds 50 pF

Compared with SN74LVC14APWR, the 74LVT14DB,118 adds bus-hold and IOFF for robustness in unconfigured or power-gated systems; versus 74LVTH14PW,118, it trades peak drive strength for lower static current and identical timing at typical loads.

FAQ

Does 74LVT14DB,118 support hot insertion in live backplanes?

Yes - its IOFF circuitry ensures outputs enter high-impedance state when VCC = 0 V, preventing back-current flow even if inputs or outputs are biased to 5 V during insertion. Input clamping current is limited to ±50 mA, and absolute maximum VI is +7.0 V, supporting safe hot-plug operation in properly current-limited systems.

Can unused inputs be left floating?

Yes - integrated bus-hold circuitry actively retains the last valid logic state on unconnected inputs, eliminating need for external pull-up or pull-down resistors. This reduces BOM cost, PCB area, and potential signal integrity issues caused by resistor parasitics.

What is the minimum input transition rate this device can reliably handle?

The device tolerates slow input transitions down to 10 ns/V (i.e., rise/fall times up to ~100 ns for a 1 V swing), thanks to Schmitt-trigger hysteresis. This makes it suitable for debouncing mechanical switches or conditioning signals from slow analog comparators without additional RC filtering.

Is the SO14 package (SOT108-1) RoHS compliant and lead-free?

Yes - the 74LVT14DB,118 in SO14 packaging meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound, verified per Nexperia's compliance documentation and material declarations.
