Product details

8-bit bus transceiver with 1.65-3.6V supply and 24 mA drive

The SN74LVCH245ADGVR is an 8-bit non-inverting transceiver from the 74LVCH family, designed for bidirectional asynchronous communication between two data buses. Its 3-state outputs let each bus be isolated independently — a standard bus-interface building block for mixed-voltage systems. Supply voltage spans 1.65 V to 3.6 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails in a single BOM line. The 24 mA source and sink drive at each output is enough to fan out to multiple CMOS loads or drive short PCB traces without an external buffer. Rated for -40°C to +125°C ambient, this part holds its timing and drive specs across the full industrial-automation temperature envelope — no derating needed for a panel that sees 85°C internal air.

Package and mounting for PCB layout

Housed in a 20-TVSOP package (4.40 mm width, 0.173" body) with 0.65 mm pin pitch. The surface-mount footprint is shared with the standard TSSOP-20 land pattern — no special pad geometry required. Tape & Reel (TR) and Cut Tape (CT) options cover both production reels and prototype quantities.

Frequently asked questions

Will SN74LVCH245ADGVR drop into a board laid out for SN74LVTH16245ADGVR?

The SN74LVTH16245ADGVR is a 16-bit transceiver in a 48-pin package, so it is not pin-compatible with this 20-pin 8-bit part. The supply-voltage range also differs: the LVCH part accepts 1.65-3.6 V, while the LVTH16245 requires a minimum of 2.7 V. A board designed for the 16-bit part would need a different footprint and voltage rail.
