8 Limiting values
Table 5. Limiting values are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C. [2] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
9 Recommended operating conditions
Table 6. Operating conditions Voltages are referenced to GND (ground = 0 V).
10 Static characteristics
Table 7. Static characteristics Tamb = -40 °C to +85 °C. Voltages are referenced to GND (ground = 0 V). [1] All typical values are measured at VCC = 5 V; Tamb = 25 °C. [2] This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND. lowest voltage of the two (A or B) terminals.
11 Dynamic characteristics
Table 8. Dynamic characteristics Tamb = -40 °C to +85 °C; Voltages are referenced to GND (ground = 0 V); for test circuit see Figure 8. switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance). [2] tpd is the same as tPHL and tPLH. [3] ten is the same as tPZH and tPZL.
11.1 Waveforms and test circuit
Measurement points are given in Table 9. VOL and VOH are typical output voltage levels that occur with the output load. Figure 6. The data input (A) to output (nYn) propagation delay times
Measurement points are given in Table 9. VOL and VOH are typical output voltage levels that occur with the output load. Figure 7. Enable and disable times Table 9. Measurement points
The outputs are measured one at a time with one transition per measurement. CL = Load capacitance including jig and probe capacitance. RT = Termination resistance should be equal to the output impedance Zo of the pulse generator. VEXT = External voltage for measuring switching times. Figure 8.
