74LS138 Datasheet 1-of-8 Decoder/demultiplexer

Manufacturer: Unknown Manufacturer

Overview: www.DataSheet4U.com SN74LS138 1-of-8 Decoder/ Demultiplexer The LSTTL / MSI SN74LS138 is a high speed 1-of-8 Decoder / Demultiplexer.

Datasheet Details

three Enable inputs, two active LOW (E1, E2) and one active HIGH (E3). All outputs will be HIGH unless E1 and E2 are LOW and E3 is HIGH. This multiple enable function allows easy parallel expansion of the device to a 1-of-32 (5 lines to 32 lines) decoder with just four LS138s and one inverter. (See Figure a. ) The LS138 can be used as an 8-output demultiplexer by using one of the active LOW Enable inputs as the data input and the other Enable inputs as strobes. The Enable inputs which are not us.
