Nexperia 74HCT138D,653, Dekoder ve Çoklayıcı (MUX) Yongası, 08-Mar, Inv, 16-Pinli SSOP

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). Every output will be HIGH 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 ’138’ ICs and one inverter. The ’138’ 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.

• Multiple input enable for easy expansion or independent controls
• Integrated input latch to store the address of decoder lines
• Ideal for memory chip select decoding
• Asynchronous and synchronous load options
• Overvoltage tolerant input options
• Inverting and non-inverting output options
• 3-stage outputs
• High frequency
