Product details

Active production part with automotive qualification

The SN74HC14QDRG4Q1: It is an AEC-Q100 qualified device (Automotive, 74HC series), meaning it passed the reliability stress, temperature cycling, and PPAP requirements for automotive-grade ICs.

Six Schmitt-trigger inverters, 2V to 6V supply

Six independent inverter gates, each with a Schmitt-trigger input that provides hysteresis between the low-level threshold (0.3V to 1.2V) and high-level threshold (1.5V to 4.2V). This built-in noise immunity means a slowly rising or noisy input signal won't cause multiple output transitions — the part cleans up a dirty clock or sensor line without external RC filtering. Output drive is 5.2 mA source and sink at the rated supply — enough to drive a downstream logic input or a low-current LED directly, but not a relay coil or high-capacitance bus without a buffer.

14-SOIC footprint, surface-mount assembly

Packaged in a 14-SOIC (0.154-inch body width, 3.90 mm width), supplier device package 14-SOIC. The 1.27 mm pitch is layout-friendly — two-layer boards fan out the pins without vias.

Frequently asked questions

Where can I buy SN74HC14QDRG4Q1 and how do I get a price?

Sourced through independent and authorized distribution channels. Submit an RFQ for a firm price and lead time.

Will SN74HC14QDRG4Q1 drop into a board that was specified around SN74HCS04PWR without rewiring?

Both are hex inverters in 14-SOIC packages with Schmitt-trigger inputs, so the footprint matches. The SN74HCS04PWR is from the 74HCS series and specifies a 16 ns max propagation delay at 6V, 50 pF versus 21 ns for the SN74HC14QDRG4Q1. If the timing budget can absorb the extra 5 ns per gate, the pinout is identical and no board spin is needed. The SN74HC14QDRG4Q1 also carries AEC-Q100 automotive qualification, which the SN74HCS04PWR does not.

What compliance documentation does Texas Instruments provide for SN74HC14QDRG4Q1?

The part is ROHS3 Compliant per Texas Instruments. Standard TI documentation includes the datasheet, application notes, and PCN notifications. No UL or IEC certification is listed for this logic IC — those standards apply to end equipment, not individual semiconductor devices.
