SN74LS691DW Overview


The device is packaged in the SOICtype. This configuration uses 20terminations. 5Vis enabled to operate in an extremely flexible manner due to its supply voltage. In this case, it emerges as a member of the LS family. There is information in the device in the form of 4bits. The result may be noin terms of Pbfree code. When it comes to this electronic device, REGISTER/COUNTER OUTPUT SELECT; TCO OUTPUT; REGISTERED OUTPUTS are much important features. It is manufactured in the temperature grade COMMERCIAL. Supply voltage (Vsup) can be as low as 4.75V. It is possible to supply voltages up to 5.25V volts (Vsup). This electronic component is from the Counters family. BINARY COUNTER refers to the type of logic IC it is using. Typically, the maximum operating temperature is set to 70°C.
