The two 4-input 0 1 Common select inputs multiplexer circuits have individual 2Y = 2E.(2I .S .S +2I .S .S + 0 1 0 1 1 0 See 253 for 3-state version active LOW output enable inputs (1E, +2I .S .S +2I .S .S ) 2 1 0 3 1 0 Permits multiplexing from n lines to 2E) which can be used to strobe the The 153 can be used to move data 1 line outputs independently. The outputs to a common output bus from a group Enable line provided for cascading (1Y, 2Y) are forced LOW when the of registers. The state of the select (n lines to 1 line) corresponding output enable inputs inputs would determine the particular are HIGH. Output capability: standard register from which the data came. An The 153 is the logic implementation alternative application is a function I category: MSI CC of a 2-pole, 4-position switch, where generator. The device can generate the position of the switch is two functions or three variables. This GENERAL DESCRIPTION determined by the logic levels applied is useful for implementing highly to S and S . irregular random logic. 0 1 The 74HC/HCT153 are high-speed Si-gate CMOS devices and are pin The 153 is similar to the 253 but compatible with low power Schottky has standard outputs. TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
