16-bit bus transceiver with 1.65V-3.6V range
The SN74ALVCH16245DL is a 16-bit non-inverting transceiver from TI's 74ALVCH series, organized as two 8-bit elements with independent direction controls. It operates across a 1.65V to 3.6V supply range, making it suitable for mixed-voltage systems where a 1.8V or 2.5V core bus needs to drive a 3.3V peripheral bus. Each channel sources or sinks 24mA, enough to drive a standard CMOS load or a lightly loaded backplane trace without an external buffer. The 3-state outputs allow multiple transceivers to share a common data bus — the outputs go high-impedance when the output-enable pin is deasserted.
Package and temperature grade
Housed in a 48-lead SSOP (0.295-inch body width, 0.635mm pitch), the SN74ALVCH16245DL's footprint matches the standard 48-BSSOP land pattern.
