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.
Current drive capability is 12mA at the outputs.
