Quad buffer for 5V bus isolation
It operates from a 4.5V to 5.5V supply and is packaged in a 14-SOIC surface-mount package. The commercial temperature range (0°C to 70°C) suits it for office equipment, appliance controllers, and indoor PCB-level signal distribution where 5V logic is the standard.
Each buffer can source 15 mA and sink 64 mA, giving it the headroom to drive a heavily loaded 5V bus or multiple CMOS inputs without external line drivers. The 3-state outputs let multiple buffers share a common data line — the output enable per channel is independent, so you can gate each signal individually.
