Product Details
The 74HC138, 74HCT138 decodes three binary weighted address inputs (A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable inputs (E1, E2 and E3). Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH. This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines) decoder with just four 138 ICs and one inverter. The 138 can be used as an eight output demultiplexer by using one of the active LOW enable inputs as the data input and the remaining enable inputs as strobes.
Multiple input enable for easy expansion or independent controls
Integrated input latch to store the address of decoder lines
Ideal for memory chip select decoding
Asynchronous and synchronous load options
Overvoltage tolerant input options
Inverting and non-inverting output options
3-stage outputs
High frequency
Can be cascaded
Key applications
Selection of memory banks and peripherals
