AZV99
MLP 8, 2x2 mm Package, NA, NB & ND Options
The MLP 8 NA, NB and ND options of the AZV99 provide a PECL/ECL level enable input (¯E¯N¯). When the
¯E¯N¯ input is LOW, the Q¯ and QHG/Q¯HG outputs pass data from the inputs. When ¯E¯N¯ is HIGH, the Q¯ output
continues to pass data while the QHG output is forced high and the Q¯HG output is forced low.
Only the Q¯ output operates with a current source (4 mA) to VEE. This is accomplished by internal bonding of
CS-SEL. An external resistor may also be used to increase pull-down current to a maximum of 25mA (includes
4mA on-chip current source).
The AZV99NB and AZV99ND versions operates with a single ended data input (D). The D¯ input is internally
bonded directly to the VBB pin bypassing the 470Ω bias resistor.
TSSOP 8 Package (T), MLP 8 Package, (N)
The TSSOP 8 (T) and MLP 8 (N) versions of the AZV99 provide a CMOS/TTL level enable input (EN). When
the EN input is HIGH, the Q¯ and QHG/Q¯HG outputs pass data from the inputs. When EN is LOW, the Q¯ output
continues to pass data while the QHG output is forced high and the Q¯HG output is forced low.
Only the Q¯ output operates with a current source (4 mA) to VEE. This is accomplished by internal bonding of
CS-SEL. An external resistor may also be used to increase pull-down current to a maximum of 25mA (includes
4mA on-chip current source).
The TSSOP 8 (T) and MLP 8 (N) AZV99 operates with a single ended data input (D). The D¯ input is internally
bonded directly to the VBB pin bypassing the 470Ω bias resistor.
NOTE: Specifications in the ECL/PECL tables are valid when thermal equilibrium is established.
