INTEGRATED CIRCUITS 74F157*, 74F157A, 74F158*, 74F158A Data selectors/multiplexers * Discontinued part. Please see the Discontinued Product List in Section 1, page 21. 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. 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 DESCRIPTION 16-pin plastic DIP 16-pin plastic SO COMMERCIAL RANGE VCC = 5V ±10%, Tamb = 0...
