Nexperia B.V. Signal Switches, Multiplexers, Decoders 74HC138DB,112

The 74HC138DB,112 is a 3-to-8 line decoder/demultiplexer from Quarktwin Technology Ltd. It decodes three binary weighted address inputs (A0, A1, A2) into eight mutually exclusive outputs (Y0 to Y7). The device includes three enable inputs (E1, E2, E3), allowing for flexible control of the outputs, which will be HIGH unless E1 and E2 are LOW and E3 is HIGH. This feature enables easy parallel expansion to a 1-of-32 decoder configuration using multiple '138 ICs. The product operates within a wide supply voltage range of 2.0 to 6.0 V and is designed with CMOS technology for low power dissipation and high noise immunity. It also features input clamp diodes, which facilitate interfacing with voltages exceeding V_CC using current limiting resistors. The 74HC138DB,112 is specified for operation over a temperature range of -40 ¬8C to +125 ¬8C and offers ESD protection exceeding 2000 V for HBM and 200 V for MM. Multiple package options are available, including SO16, TSSOP16, and DHVQFN16 configurations.
