Revised April 1999 74VHC153 Dual 4-Input Multiplexer General Description The VHC153 is an advanced high-speed CMOS device fabricated with silicon gate CMOS technology. It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHC153 is a high-speed Dual 4-Input Multiplexer with common select inputs and individual enable inputs for each section. It can select two lines of data from four sources. The two buffered outputs present data in the true (non-inverted) form. In addition to multiplexer operation, the VHC153 can act as a function generator and generate any two functions of three variables. An input protection circuit insures that 0V to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages.

It can select two bits of data from up to four sources under the control of the common Select inputs (S0, S1). The two 4-input multiplexer circuits have individual active-LOW Enables (Ea, Eb) which can be used to strobe the outputs independently. When the Enables (Ea, Eb) are HIGH, the corresponding outputs (Za, Zb) are forced LOW. The VHC153 is the logic implementation of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels supplied to the Select inputs. The logic equations for the outputs are shown below.
