SN74LS153 Dual 4-Input Multiplexer The LSTTL / MSI SN74LS153 is a very high speed Dual 4-Input Multiplexer with common select inputs and individual enable inputs for each section. It can select two bits of data from four sources. The two buffered outputs present data in the true (non-inverted) form. In addition to multiplexer operation, the LS153 can generate any two functions of three variables. The LS153 is fabricated with the Schottky barrier diode process for high speed and is completely compatible with all ON Semiconductor TTL families. • • • • http://onsemi.com LOW POWER SCHOTTKY Multifunction Capability Non-Inverting Outputs Separate Enable for Each Multiplexer Input Clamp Diodes Limit High Speed Termination Effects GUARANTEED OPERATING RANGES Symbol VCC Parameter Supply Voltage Min Typ Max Unit 4.75 5.0 5.25 V 0 25 70 °C TA Operating Ambient Temperature Range IOH Output Current – High – 0.4 mA IOL Output Current – Low 8.0 mA 16 1 PLASTIC N SUFFIX CASE 648 16 1 SOIC D SUFFIX CASE 751B ORDERING INFORMATION Semiconductor Components Industries, LLC, 1999 December, 1999 – Rev. 6 1 Device Package Shipping SN74LS153N 16 Pin DIP 2000 Units/Box SN74LS153D 16 Pin 2500/Tape & Reel Publication Order Number: SN74LS153/D SN74LS153 CONNECTION DIAGRAM DIP (TOP VIEW) VCC Eb S0 I3b I2b I1b I0b Zb 16 15 14 13 12 11 10 9 NOTE: The Flatpak version has the same pinouts (Connection Diagram) as the Dual In-Line Package. 1 Ea 2 S1 3 I3a 4 I2a 5 I1a 6 I0a 7 Za 8 GND LOADING (Note a) PIN NAMES S0 E I0, I1 Z Common Select Input Enable (Active LOW) Input Multiplexer Inputs Multiplexer Output HIGH LOW 0.5 U.L. 0.5 U.L. 0.5 U.L. 10 U.L. 0.25 U.L. 0.25 U.L. 0.25 U.L. 5 U.L.

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 LS153 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 two Select Inputs. The logic equations for the outputs are shown below. Zb = Eb ⋅ (I0b ⋅ S1 ⋅ S0 + I1b ⋅ S1 ⋅ S0 + I2b ⋅ S1 ⋅ S0 + I3b ⋅ S1 ⋅ S0) The LS153 can be used to move data from a group of registers to a common output bus. The particular register from which the data came would be determined by the state of the Select Inputs. A less obvious application is a function generator. The LS153 can generate two functions of three variables. This is useful for implementing highly irregular random logic.
