NXP Semiconductors 74F157A
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.| Part No. | 74F157A |

DESCRIPTION
The Enable input (E) is active when Low. Moving data from two registers to a common output bus is a common use of the 74F157A. The state of the Select input determines the particular register from which the data comes. The device is the logic implementation of a 4-pole, 2-position switch where the position of the switch is determined by the logic levels supplied to the Select input. The 74F158A is similar, but has inverting outputs (Yn). 74F157A, 74F158A Quad 2-input data selector/multiplexer, non-inverting Quad 2-input data selector/multiplexer, inverting● Industrial temperature range (–10°C to +85°C) available for 74F157A TYPICAL PROPAGATION DELAY 4.6ns 4.6ns 3.7ns 3.7ns TYPICAL SUPPLY CURRENT (TOTAL) 15mA 15mA 10mA 10mA TYPE 74F157 74F157A 74F158 74F158A ORDERING INFORMATION ORDER CODE
