CD40257B - CMOS Quad 2-Line-to-1-Line Data Selector/Multiplexer

CD40257B is a Data Selector/Multiplexer featuring three-state outputs which can interface directly with and drive data lines of bus-oriented systems.

The CD40257B types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
