1-of-10 decoder
Philips Semiconductors Product specification
1-of-10 decoder HEF4028B
MSI
DESCRIPTIONThe HEF4028B is a 4-bit BCD to 1-of-10 active HIGH
decoder. A 1-2-4-8 BCD code applied to inputs A0 to A3
causes the selected output to be HIGH, the other nine will
be LOW. If desired, the device may be used as a 1-of-8
decoder with enable; 3-bit octal inputs are applied to inputs
A0, A1 and A2 selecting an output O0 to O7. Input A3 then
becomes an active LOW enable, forcing the selected
output LOW when A3 is HIGH. The HEF4028B may also
be used as an 8-output (O0 to O7) demultiplexer with A0 to
A2 as address inputs and A3 as an active LOW data input.
The outputs are fully buffered for best performance.
