Single-gate inverter for 5V logic busses
The SN74AHCT1G04DCKT is a single-channel inverter from Texas Instruments' 74AHCT series, designed for 4.5V to 5.5V supply rails. It delivers 8mA source and sink output drive, enough to switch a standard CMOS load or drive a short trace on a mixed-voltage backplane without a buffer. Input logic thresholds are set at 0.8V low and 2V high, making it directly compatible with 5V TTL outputs — no level translation needed at the gate input. The 9ns max propagation delay at 5V into 50pF keeps the signal clean for bus speeds up to about 50 MHz, though the real limit is the output rise time into the load capacitance.
Package, footprint, and temperature range
Housed in a 5-lead SC-70-5 (SOT-353) package, the part occupies roughly 2.0 × 2.1 mm on the board. The 0.65 mm pin pitch fans out easily on a two-layer board — no fine-line routing required. Surface-mount assembly with standard reflow profiles; the package is compatible with both leaded and lead-free solders. Rated for -40°C to 125°C ambient operation, this inverter covers the full industrial temperature band. The quiescent current maxes out at 1 µA, so it won't tax the 5V rail in a power-sensitive design.
Lifecycle and compliance
RoHS3 compliance means it meets the latest EU restriction limits for lead, mercury, cadmium, and other substances. The part is supplied in Tape & Reel or Cut Tape options for pick-and-place assembly.
Sourcing and availability
This TI inverter is sourced through independent distribution channels. Pricing and lead time are confirmed at quote time against the specific BOM quantity. No minimum order quantity restrictions apply for standard reel quantities.
