Product details

What the 32 mA / 64 mA drive tells you about the load

The SN74LVT245BDB: This is an 8-bit non-inverting transceiver with 3-state outputs — it passes data bidirectionally under a direction control pin and floats the bus when the output enable is deasserted. The 32 mA source and 64 mA sink capability at 3.3 V means it can drive a heavily loaded backplane or a bank of CMOS inputs without external buffers, as long as the total capacitive load per line stays within the propagation delay budget.

Package and temperature range — board-fit check

Housed in a 20-SSOP (0.209″, 5.30 mm width) package, the SN74LVT245BDB mounts on a standard surface-mount footprint with 0.65 mm pitch.

Frequently asked questions
