The 74HC238D is a 3-to-8 Decoder/Demultiplexer 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\ and E2\ and E3). Every output will be low unless E1\ and E2\ are low and E3 is high. This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines) decoder with just four 238 ICs and one inverter. The 238 can be used as an eight output demultiplexer by using one of the active low enable inputs as the data input and the remaining enable inputs as strobes. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
● Demultiplexing capability
● Multiple input enable for easy expansion
● Ideal for memory chip select decoding
● Active high mutually exclusive outputs
● CMOS Input level
● Complies with JEDEC standard No. 7A
