Document Summary
Digital input(s): data inputs: w(msb), x, y, and z(lsb) from switches, select lines: none, clock: none. Pin #14 | #16 chip #: 74ls08 20 | 74ls138. Extra questions: find or calculate the values of the following parameters for the 74ls04. Vih = 2v, na, na: input low voltage. = na, 18ma, 33ma (l: average power dissipation. Tphl = (na, 8ns, 15ns: find or calculate the values of the following parameters for the 74ls138. Voh = 2. 7v, 3. 5v, na: output low voltage. Vol = na, 0. 25v, 0. 4v (iol = 4. 0ma) = na, 0. 35v, 0. 5v (iol = 8. 0ma: supply voltage. Icc = na, na, 10ma: average power dissipation. Tphl = (na, 25ns, 38ns: find or calculate the values of the following parameters for the 74ls153. The answers should be in the following format: Use na for not available: input high voltage. Vih = 2. 0v, na, na: input low voltage. Vil = na, na, 0. 8v: output high voltage.
