N74F158AN,602 DESCRIPTION

The 74F157A is a high speed Quad 2-Input Multiplexer whichselects 4 bits of data from one of two sources under the control of acommon Select input (S). The Enable input (E) is active when Low.When E is High, all of the outputs (Yn) are forced Low regardless ofall other input conditions.Moving data from two registers to a common output bus is acommon use of the 74F157A. The state of the Select inputdetermines the particular register from which the data comes.The device is the logic implementation of a 4-pole, 2-position switchwhere the position of the switch is determined by the logic levelssupplied to the Select input.The 74F158A is similar, but has inverting outputs (Yn). • Industrial temperature range (–10°C to +85°C) available for
