MC74LCX138

Low−Voltage CMOS 3−to−8

Decoder/Demultiplexer

With 5 V−Tolerant Inputs

The MC74LCX138 is a high performance, 3−to−8

decoder/demultiplexer operating from a 2.3 to 3.6 V supply. High

impedance TTL compatible inputs significantly reduce current

loading to input drivers while TTL compatible outputs offer improved

switching noise performance. A V specification of 5.5 V allows

MC74LCX138 inputs to be safely driven from 5 V devices. The

MC74LCX138 is suitable for memory address decoding and other

TTL level bus−oriented applications.

The MC74LCX138 high−speed 3−to−8 decoder/demultiplexer

accepts three binary weighted inputs (A0, A1, A2) and, when enabled,

provides eight mutually exclusive active−LOW outputs (O0−O7). The

LCX138 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 LCX138 devices and one inverter (see

Figure 1). The LCX138 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.
