These device consist of four 2-input digital multiplexer with common select and strobe inputs. When the STROBE input is held high, selection of data is inhibited and all the outputs become low. ) (s t c u DIP PACKAGE TUBE t e l o s b O TSSOP u d o r P e ORDER CODES DIP SOP TSSOP ) s ( ct SOP M74HC157B1R M74HC157M1R T&R M74HC157RM13TR M74HC157TTR The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. All inputs are equipped with protection circuits against static discharge and transient excess voltage. d o r P e t e l o s b O PIN CONNECTION AND IEC LOGIC SYMBOLS July 2001 1/9 M74HC157 INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No SYMBOL NAME AND FUNCTION 1 SELECT 2, 5, 11, 14 1A to 4A Common Data Select Input Data Inputs From 3, 6, 10, 13 1B to 4B Source A Data Inputs From 4, 7, 9, 12 15 8 16 1Y to 4Y STROBE GND VCC Source B Multiplexer Output Strobe Inputs Ground (0V) Positive Supply Voltage u d o TRUTH TABLE INPUTS STROBE SELECT A H L L L L X L L H H X L H X X s ( t c u d o r P e t e l o s b O 2/9 e t e l o s b O ) X : Don’t Care LOGIC DIAGRAM B X X X L H ) s ( ct Pr OUTPUTS Y L L H L H M74HC157 ABSOLUTE MAXIMUM RATINGS Symbol VCC Parameter Value Supply Voltage Unit -0.5 to +7 V -0.5 to VCC + 0.5 -0.5 to VCC + 0.5 V DC Input Diode Current ± 20 mA IOK DC Output Diode Current ± 20 mA IO DC Output Current ± 25 mA ± 50 mA 500(*) mW VI DC Input Voltage VO DC Output Voltage IIK ICC or IGND DC VCC or Ground Current PD Power Dissipation Tstg Storage Temperature TL Lead Temperature (10 sec) V ) s ( t -65 to +150 300 c u d °C °C Absolute Maximum Ratings are those values beyond which damage to the device may occur.
