Ic chips: 74HCT138N 3-to-8 decoder/demultiplexer invert
- Multiple input enable for easy expansion
- Ideal for memory chip select decoding
- Active LOW mutually exclusive outputs
- The 74HCT138N are high-speed Si-gate CMOS
devices and are pin compatible with low
- They are specified in compliance with
- The 74HCT138N are four non-inverting buffer/line drivers with 3-state outputs.
- This multiple enable function allows easy parallel expansion of the 138 to a 1-of-32 (5 lines 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. Unused enable inputs must be permanently tied to their appropriate active HIGH or LOW state.
