SN74HC244QPWRQ1
Texas InstrumentsSN74HC244QPWRQ1 is an automotive octal buffer and line driver with 3-state outputs from Texas Instruments in a 20-pin TSSOP package, for automotive digital signal buffering. It operates from 2–6 V with two independent 4-bit output-enable controls. Selection advice: this is the automotive Q1 variant — do not substitute the catalog SN74HC244 (non-Q) or the SN74HCT244/AHCT244 family members (different input thresholds). Note: TI lifecycle status badge not confirmed on the product page at time of review; orderable via TI.

SN74HC244QPWRQ1 FAQ
Is SN74HC244QPWRQ1 automotive-qualified?
The SN74HC244QPWRQ1 ordering code carries the manufacturer's automotive qualification marker. Qualification grade, temperature range and PPAP documentation depend on the exact lot offered, so state your automotive documentation requirements (PPAP level, AEC test reports) in the RFQ and we will confirm them against the offered lot before quotation.
What should I check before substituting SN74HC244QPWRQ1 with another Buffer/line driver?
Match the full ordering code, not the series name: package (TSSOP-20), temperature grade and packing all ride on the suffixes. A same-series code in a different package is a different orderable device, so confirm the substitute against the Texas Instruments datasheet before changing the BOM.
