The IN74ACT258

      The IN74ACT258 is one kind of Quad 2-Input Data Selector/Multiplexer with 3-State Outputs,it is identical in pinout to the LS/ALS258, HC/HCT258. The IN74ACT258 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.This device selects a (4-bit) nibble from either the A or B inputs as determined by the Select input. The nibble is presented at the outputs in inverted from when the Output Enable pin is at a low level. A high level on the Output Enable pin switches the outputs into the high-impedance state.
      Features of IN74ACT258 are as follows:(1)TTL/NMOS Compatible Input Levels;(2)Outputs Directly Interface to CMOS, NMOS, and TTL;(3)Operating Voltage Range: 4.5 to 5.5 V;(4)Low Input Current: 1.0 A; 0.1 A @ 25°C;(5)Outputs Source/Sink 24 mA.
      Here are the maximum ratings of The IN74ACT258:(1)DC Supply Voltage is -0.5 to +7.0V;(2)DC Input Voltage:-0.5 to VCC +0.5V;(3)DC Output Voltage:-0.5 to VCC +0.5V;(4)DC Input Current, per Pin:±20mA;(5)DC Output Sink/Source Current, per Pin:±50mA;(6)DC Supply Current, VCC and GND Pins:±50mA;(7)Storage Temperature:-65 to +150°C;(8)Lead Temperature, 1 mm from Case for 10 Seconds:260°C.
      These are recommended operating conditions of The IN74ACT258:(1)DC Supply Voltage is 4.5-5.5V;(2)Junction Temperature is 140°C;(3)Operating Temperature, All Package Types is -40-+85°C;(4)Output Current is -24 to 24mA.
