Sibling variants, package options, and speed/density grades in this NXP Semiconductors semiconductor series. Active Shenzhen warehouse allocation and rapid 24-48h dispatch.
The maximum propagation delay is 28 ns at 4.5 V with a 50 pF load. Quiescent current is a maximum of 2 µA, which matters for battery-backed or always-on domains where the gate sits idle most of the time. The output drive is symmetric at 4 mA sink and source, enough to drive one or two standard CMOS loads but not a long backplane trace or a high-capacitance bus.
Buyers need exact cost for BOM and budget approval.
Sourcing buyers need immediate availability to avoid line-down situations.
Design engineers and brokers need alternatives if part is constrained or obsolete.
Engineers need to verify footprint and compatibility when designing in or replacing.
Buyers need to choose between HCT vs HC families for voltage level and speed compatibility.
Production planners need lead time to schedule manufacturing and avoid delays.
