SN54157J

The SN54157J is one member of the SN54157 family which is designed as the quadruple 2-line to 1-line data selector / multiplexer that can supply full on-chip data selection to the four output gates. SN54157J can be used in expand any data input point, multiplex dual data buses, generate four functions of two variables (one variable is common) and source programmable counters applications.

Features of the SN54157J are:(1)buffered inputs and outputs;(2)three speed / power ranges available. The absolute maximum ratings of the SN54157J can be summarized as:(1)supply voltage, Vcc: 7 V;(2)input voltage: 5.5 V;(3)operating free-air temperature range: -55 to +125 ;(4)storage temperature range: -65 to +150 .

The electrical characteristics of this device can be summarized as:(1)high-level input voltage: 2 V;(2)low-level input voltage: 0.8 V;(3)input clamp voltage: 1.5 V;(4)high-level output voltage: 2.4 to 3.4 V;(5)low-level output voltage: 0.2 to 0.4 V;(6)input current at maximum input voltage: 1 mA;(7)high level input current: 40 uA;(8)low-level input current: -1.6 mA;(9)short circuit output current: -20 to -55 mA;(10)supply current: 30 to 48 mA.
