3.3 V octal D-type transparent latch; (3-state)
11. Waveforms
Measurement points are given in Table 8.
Fig 6.
Propagation delays latch enable input (LE) to
output (Qn), and latch enable (LE) pulse width
Fig 7.
Propagation delay data input (Dn) to
output (Qn)
Measurement points are given in Table 8.
VOL and VOH are typical voltage output levels that occur
with the output load.
Measurement points are given in Table 8.
Fig 8.
Output enable time to HIGH-state and output
disable time from HIGH-state
Fig 9.
Output enable time to LOW-state and output
disable time from LOW-state
Measurement points are given in Table 8.
Remark: The shaded areas indicate when the input is permitted to change for predictable output performance.
