Active production, 5 V bus transceiver
The SN74HCT245NSR: It is an 8-bit non-inverting transceiver with 3-state outputs, operating from a 4.5 V to 5.5 V supply — the standard 5 V TTL-compatible rail used in legacy and mixed-voltage industrial logic buses.
Output drive and temperature grade
The high and low output current is rated at 6 mA each — this sets the fan-out limit for the downstream loads; each output can drive up to six standard LSTTL inputs or a single 5 V CMOS gate with margin. The operating temperature range spans -40°C to 85°C (TA), the industrial grade that covers factory-floor enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics without a commercial-temperature waiver.
Package and assembly fit
Housed in a 20-SOIC package with a 5.30 mm body width (0.209"), the SN74HCT245NSR mounts on the standard SOIC-20 footprint and ships on tape and reel for automated pick-and-place — the reel format suits volume production runs. The supplier device package is 20-SO; the board layout matches the JEDEC MS-013 variation for the 5.30 mm-wide SOIC body.
Compliance and sourcing posture
ROHS3 compliant — no restricted substances above the exemption thresholds, so the part passes into European and California-regulated supply chains without a waiver review.
