6 / 7 page December 1990 6 Philips Semiconductors Product specification Quad 2-input multiplexer 74HC/HCT157 DC CHARACTERISTICS FOR 74HCT For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”. Output capability: standard ICC category: MSI Note to HCT types The value of additional quiescent supply current ( ∆ICC) for a unit load of 1 is given in the family specifications. To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below. AC CHARACTERISTICS FOR 74HCT GND = 0 V; tr = tf = 6 ns; CL = 50 pF INPUT UNIT LOAD COEFFICIENT nI0 nI1 E S 1.00 1.00 0.60 1.00 SYMBOL PARAMETER Tamb (°C) UNIT TEST CONDITIONS 74HCT VCC (V) WAVEFORMS +25 −40 to +85 −40 to +125 min. typ. max. min. max. min. max. tPHL/ tPLH propagation delay nI0 to nY; nI1 to nY 16 27 34 41 ns 4.5 Fig.7 tPHL/ tPLH propagation delay E to nY 15 26 33 39 ns 4.5 Fig.6 tPHL/ tPLH propagation delay S to nY 22 37 46 56 ns 4.5 Fig.7 tTHL/ tTLH output transition time 7 15 19 22 ns 4.5 Fig.6 and Fig.7 |
