描述 Description

The Radiation Hardened ACS257MS is a Quad 2-Channel multiplexer which selects four bits of data from one of two sources under the control of a single select pin. The Output Enable input is active LOW and controls all outputs. When OE is set HIGH, all outputs are configured into a high impedance state, regardless of all other input conditions. All inputs are buffered and the outputs are designed for balanced propagation delay and transition times.
