5V logic buffer with extended temperature range
This is a 74HCT-series non-inverting buffer organized as two elements of four bits each, with 3-state outputs that let you disable the bus drivers for shared-line applications. The supply range is 4.5V to 5.5V, which makes it a direct drop-in for 5V TTL-level systems — the HCT family is designed for TTL-compatible input thresholds while running on a 5V rail. Output drive is rated at 6 mA source and 6 mA sink, sufficient for driving a standard CMOS load or a few TTL gate inputs.
20-SOIC footprint and surface-mount assembly
The package is a 20-SOIC with a 7.50 mm body width, supplier device package 20-SO. It is a surface-mount part, so the board layout uses a standard SOIC-20 footprint with 1.27 mm pitch. The shipping medium is Bulk, which means the parts arrive in tubes or loose in a bag — not on a reel — so factor that into your pick-and-place feeder setup if you are running a high-volume line.
