Nexperia B.V. Integrated Circuits (ICs) - Logic - Signal Switches, Multiplexers, Decoders 74HCT138D,653

The 74HCT138D,653 is a 3-to-8 line decoder/demultiplexer that converts three binary weighted address inputs (A0, A1, A2) into eight mutually exclusive outputs (Y0 to Y7). It features three enable inputs (E1, E2, E3), allowing for flexible control of the outputs. The device outputs are HIGH by default unless E1 and E2 are LOW and E3 is HIGH, enabling easy parallel expansion to a 1-of-32 decoder configuration with additional '138 ICs and an inverter. This component operates within a wide supply voltage range of 2.0 to 6.0 V and is designed for low power dissipation, making it suitable for battery-operated devices. It has high noise immunity and complies with JEDEC standards, ensuring reliable performance in various applications. The 74HCT138D,653 is specified for operation in temperatures ranging from -40 °C to +125 °C and is available in multiple package options, including SO16 and TSSOP16. The device also includes input clamp diodes for interfacing with higher voltages, enhancing its versatility in circuit designs.
