SEMICONDUCTOR TECHNICAL DATA " ! ! # LVQ The MC74LVQ138 is a high performance, 1–of–8 decoder/ demultiplexer operating from a 2.7 to 3.6V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. The MC74LVQ138 is suitable for memory address decoding and other TTL level bus oriented applications. The MC74LVQ138 high–speed 1–of–8 decoder/demultiplexer accepts three binary weighted inputs (A0, A1, A2) and, when enabled, provides eight mutually exclusive active–LOW outputs (O0–O7). The LVQ138 features 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 enabled function allows easy parallel expansion of the device to a 1–of–32 (5 lines to 32 lines) decoder with just four LVQ138 devices and one inverter (See Figure 1). The LVQ138 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 used must be permanently tied to their appropriate active–HIGH or active–LOW state.
