Product data sheet Rev. 03 — 11 November 2004 2 of 20 Philips Semiconductors 74HC283 4-bit binary full adder with fast carry 3. Quick reference data [1] CPD is used to determine the dynamic power dissipation (PD in µW). PD =CPD × VCC2 × fi × N+ ∑(CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in V; N = number of inputs switching; ∑(C L × VCC 2 × f o) = sum of outputs. 4. Ordering information Table 1: Quick reference data GND = 0 V; Tamb =25 °C; tr =tf = 6 ns. Symbol Parameter Conditions Min Typ Max Unit tPHL, tPLH propagation delay CL = 15 pF; VCC =5 V CIN to S1 - 16 - ns CIN to S2 - 18 - ns CIN to S3 - 20 - ns CIN to S4 - 23 - ns An or Bn to Sn - 21 - ns CIN to COUT - 20 - ns An or Bn to COUT - 20 - ns CI input capacitance - 3.5 - pF CPD power dissipation capacitance VI = GND to VCC [1] -88 - pF Table 2: Ordering information Type number Package Temperature range Name Description Version 74HC283N −40 °C to +125 °C DIP16 plastic dual in-line package; 16 leads (300 mil) SOT38-4 74HC283D −40 °C to +125 °C SO16 plastic small outline package; 16 leads; body width 3.9 mm SOT109-1 74HC283DB −40 °C to +125 °C SSOP16 plastic shrink small outline package; 16 leads; body width 5.3 mm SOT338-1 74HC283PW −40 °C to +125 °C TSSOP16 plastic thin shrink small outline package; 16 leads; body width 4.4 mm SOT403-1 |
