The 74HC138; 74HCT138 is a high-speed Si-gate CMOS device is pin compatible with Low-power Schottky TTL (LSTTL).
The 74HC138; 74HCT138 decoder accepts three binary weighted address inputs (A0, A1 A3) when enabled, provides 8 mutually exclusive active LOW outputs (Y0 to Y7).
The 74HC138; 74HCT138 features three enable inputs: two active LOW (E1 E2) one active HIGH (E3). Every output is HIGH unless E1 E2 are LOW E3 is HIGH.
This multiple enable function allows easy parallel expansion of the 74HC138; 74HCT138 to a 1-of-32 (5 lines to 32 lines) decoder with just four 74HC138; 74HCT138 ICs one inverter.
The 74HC138; 74HCT138 can be used as an eight output demultiplexer by using one of the active LOW enable inputs as the data input the remaining enable inputs as strobes. Permanently tie unused enable inputs to their appropriate active HIGH- LOW-state.
The 74HC138; 74HCT138 is identical to the 74HC238; 74HCT238 but has inverting outputs.
