This ic is Inverter TTL.
Part Number: 7404, SN7404, SN74LS04
Function: HEX INVERTER
Package: DIP 14 Pin
Manufacturer: Texas Instruments
These devices contain six independent inverters.
It consists of six inverters which perform logical invert action. The output of an inverter is the complement of its input logic state, i.e., when input is high its output is low and vice versa.
Dependable Texas Instruments Quality and Reliability
Operating Condition :
1. The power supply should be given to the IC from 4.5V DC to 5.25V DC
2. The IC will consider a signal as high when the voltage of the signal is above 2V
3. The IC will consider a signal as low when the voltage of the signal is below 0.8V
4. The operating temperature of the IC should be below the 70-degree centigrade
1. IC 7404 can deliver -0.4 mA current when the output is high.
2. It can deliver 16 mA current when the output is low.
3. When the Vcc is 5V and the input signal is 5V then the IC draws 1 mA current.
4. When the Vcc is 5V and the input signal is 2.7V then the IC draws 20 to 40 micro-ampere currents.
5. When the Vcc is 5V and the input signal is 0.4V then the IC draws -1.6 mA current.
