5 / 7 page December 1990 5 Philips Semiconductors Product specification Octal bus Schmitt-trigger transceiver; 3-state 74HC/HCT7245 DC CHARACTERISTICS FOR 74HCT For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”. Output capability: bus driver 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. TRANSFER CHARACTERISTICS FOR 74HCT Voltages are referred to GND (ground = 0 V) INPUT UNIT LOAD COEFFICIENT An Bn OE DIR 0.33 0.33 1.50 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.
