Product details

Automotive-grade octal buffer with Schmitt-trigger inputs

The Texas Instruments SN74HCS244QPWRQ1 is an automotive-qualified (AEC-Q100) octal buffer from the 74HCS family, providing two elements of 4-bit non-inverting buffering with Schmitt-trigger inputs and 3-state outputs.

Schmitt-trigger inputs and 3-state outputs

Schmitt-trigger inputs provide hysteresis that cleans up slow or noisy edges — useful on long PCB traces or harness wires where signal integrity is marginal. The 3-state outputs allow the buffer to be ganged on a shared bus; the high-impedance state disconnects the outputs when the enable is deasserted, avoiding contention.

Housed in a 20-TSSOP (4.40mm width) surface-mount package, the SN74HCS244QPWRQ1 uses a standard octal-buffer footprint shared with many 74-series parts.

It is ROHS3 compliant.

Frequently asked questions

Where can I buy SN74HCS244QPWRQ1?

SN74HCS244QPWRQ1 is available to order through independent distribution. Submit an RFQ for current availability and pricing; each quote is confirmed at order time.

Is SN74HCS244QPWRQ1 automotive grade?

Yes, it is part of the Automotive, AEC-Q100 series, qualified for automotive applications.

Is SN74HCS244QPWRQ1 RoHS compliant?

Yes, it is ROHS3 Compliant.

What is the equivalent of SN74HCS244QPWRQ1?

The SN74LVC2G17QDCKRQ1 is a functionally similar automotive-grade buffer from the 74LVC family, but it is a single-gate device with 1-bit per element versus the 4-bit-per-element octal configuration of the SN74HCS244QPWRQ1. The SN74HCS244QPWRQ1 is the direct octal-buffer choice when you need 8-bit width in a single package.
