NXP Semiconductors 74HCT138D Decoder/Demultiplexer Single 3-to-8 16-Pin
The 74HCT138D is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). The decoder accepts three binary weighted address inputs (A0, A1 and A3) and when enabled, provides 8 mutually exclusive active LOW outputs (Y0 to Y7).

The 74HCT138 features three enable inputs: two active LOW (E1 and E2) and one active HIGH (E3). Every output will be HIGH unless E1 and E2 are LOW and 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 and one inverter.
