3-to-8 line decoder/demultiplexer; inverting
Rev. December 2005 Product data sheet
74HC138; 74HCT138 high-speed Si-gate CMOS device compatible with Low-power Schottky (LSTTL). 74HC138; 74HCT138 decoder accepts three binary weighted address inputs (A0, when enabled, provides mutually exclusive active outputs Y7). 74HC138; 74HCT138 features three enable inputs: active active HIGH (E3). Every output will HIGH unless HIGH. This multiple enable function allows easy parallel expansion 74HC138; 74HCT138 1-of-32 lines lines) decoder with just four 74HC138; 74HCT138 inverter. 74HC138; 74HCT138 used eight output demultiplexer using active enable inputs data input remaining enable inputs strobes. used enable inputs must permanently tied their appropriate active HIGH- LOW-state. 74HC138; 74HCT138 identical 74HC238; 74HCT238 inverting outputs.
Features
Demultiplexing capability Multiple input enable easy expansion Complies with JEDEC standard Ideal memory chip select decoding Active mutually exclusive outputs protection: EIA/JESD22-A114-C exceeds 2000 EIA/JESD22-A115-A exceeds Specified from from +125
