74F157A - Data selectors/multiplexers

General Description

The 74F157A is a high speed Quad 2-Input Multiplexer which selects 4 bits of data from one of two sources under the control of a common Select input (S).

The Enable input (E) is active when Low.

When E is High, all of the outputs (Yn) are forced Low regardless of all other input conditions.

Product specification IC15 Data Handbook 1996 Mar 12 Philips Semiconductors Philips Semiconductors Product specification Data selectors/multiplexers 74F157A: 74F158A: DESCRIPTION The 74F157A is a high speed Quad 2-Input Multiplexer which selects 4 bits of data from one of two sources under the control of a common Select input (S). The Enable input (E) is active when Low. When E is High, all of the outputs (Yn) are forced Low regardless of all other input conditions. Moving data from two registers to a common output bus is a common use of the 74F157A.
