DESCRIPTION The 74ACT158 is an advanced high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology. It consists of four 2-input digital multiplexer with common select and strobe inputs. It is an inverting multiplexer. When the STROBE input is held high selection of data is inhibit and all the outputs
become high. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. The device is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

CIN CPD
Input Capacitance Power Dissipation Capacitance (note 1)
1) CPD is defined as the value of the IC's internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x f IN + ICC/n (per circuit)
TEST CIRCUIT
CL = 50pF or equivalent (includes jig and probe capacitance) RL = R1 = 500 or equivalent RT = ZOUT of pulse generator (typically 50)
