Philips Semiconductors Product specification Octal D-type transparent latch; 3-state; inverting 74HC/HCT533 The “533” consists of eight D-type transparent latches with 3-state inverting outputs. When LE is HIGH, data at the Dn inputs enter the latches. In this condition the latches are transparent, i.e. a latch output will change state each time its corresponding D-input changes.

Philips Semiconductors Product specification Octal D-type transparent latch; 3-state; inverting 74HC/HCT533 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.
