NXP Semiconductors 74HC138
The 74HC138; 74HCT138 decodes three binary weighted address inputs (A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable inputs (E1, E2 and E3). This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines) decoder with just four ‘138’ ICs and one inverter.FEATURES AND BENEFITS
