74VHC153 Dual 4-Input Multiplexer tm Features General Description ■ High Speed: tPD = 5.0ns at TA = 25°C ■ Low power dissipation: ICC = 4µA (Max.) at TA = 25°C ■ High noise immunity: VNIH = VNIL = 28% VCC (Min.) 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. ■ Power down protection is provided on all inputs ■ Pin and function compatible with 74HC153 Ordering Information Order Number Package Number Package Description 74VHC153M M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 74VHC153SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74VHC153MTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Surface mount packages are also available on Tape and Reel.

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.
