7 / 9 page December 1990 7 Philips Semiconductors Product specification Look-ahead carry generator 74HC/HCT182 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 G0, G1, P0, P1, P2 G3 G2, P3, Cn 1.50 0.30 1.25 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 Pn to P 17 28 35 42 ns 4.5 Fig.6 tPHL/ tPLH propagation delay Cn to any output 26 43 54 65 ns 4.5 Fig.6 tPHL/ tPLH propagation delay Pn to G 20 33 41 50 ns 4.5 Fig.6 tPHL/ tPLH propagation delay Pn to Cn+n 20 33 41 50 ns 4.5 Fig.6 tPHL/ tPLH propagation delay Gn to Cn+n, Gn to G 18 32 40 48 ns 4.5 Fig.6 tTHL/ tTLH output transition time 7 15 19 22 ns 4.5 Fig.6 |
