1 / 9 page  1/9 August 2001 s HIGH SPEED: tPD = 20ns (TYP.) at VCC = 6V s LOW POWER DISSIPATION: ICC = 4µA(MAX.) at TA=25°C s HIGH NOISE IMMUNITY: VNIH = VNIL = 28 % VCC (MIN.) s SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN) s BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL s WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4028 DESCRIPTION The M74HC4028 is an high speed CMOS BCD TO DECIMAL DECODER fabricated with silicon gate C2MOS technology. A BCD code applied to the four inputs (A to D) provides a high level at the selected one of the decimal decoded outputs. An illegal BCD code such as eleven to fifteen gives a low level at all outputs. The device also can be used as 3 TO 8 LINE DECODER, when D input is assigned as a disable input. The device is useful for code conversion, address decoding, memory selection, demultiplexing, or read out decoding. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
