SL74HC253N

The SL74HC253N is one member of the SL74HC253 family which is designed as the dual 4-input data selector / multiplexer device that is compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. Features of the SL74HC253N are:(1)outputs directly interface to CMOS, NMOS, and TTL; (2)operating voltage range: 2.0 to 6.0 V; (3)low input current: 1.0 uA; (4)high noise immunity characteristic of CMOS devices.

The absolute maximum ratings of the SL74HC253N can be summarized as:(1)DC Supply Voltage (Referenced to GND): -0.5 to +7.0 V;(2)DC Input Voltage (Referenced to GND): -1.5 to VCC +1.5 V;(3)DC Output Voltage (Referenced to GND): -0.5 to VCC +0.5 V;(4)DC Input Current, per Pin: ±20 mA;(5)DC Output Current, per Pin: ±25 mA;(6)Power Dissipation in Still Air, Plastic DIP+: 750 mW;(7)Storage Temperature: -65 to +150 °C;(8)Lead Temperature, 1 mm from Case for 10 Seconds: 260 °C;(9)DC Supply Current, VCC and GND PinsL +/- 50 mA.
