Octal buffer/line driver; 3-state

Philips Semiconductors Product specification
Octal buffer/line driver; 3-state 74AL VC244
FEATURES Wide supply voltage range from 1.65to 3.6V 3.6 V tolerant inputs/outputs CMOS low power consumption Direct interface with TTL levels (2.7to 3.6V) Power-down mode Latch-up performance exceeds 250 mA Complies with JEDEC standard:
JESD8-7 (1.65to 1.95V)
JESD8-5 (2.3to 2.7V)
JESD8B/JESD36 (2.7to 3.6V) ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000V
MM EIA/JESD22-A115-A exceeds 200V.
DESCRIPTION
The 74ALVC244 is a high-performance, low-power,
low-voltage, Si-gate CMOS device and superior to most
advanced CMOS compatible TTL families.
The 74ALVC244isan octal non-inverting buffer/line driver
with 3-state outputs. The 3-state outputs are controlledby
the output enable inputs 1OE and 2OE. A HIGH on nOE
causes the outputs to assume a high-impedance
OFF-state. Schmitt-trigger action at all inputs makes the
circuit highly tolerant for slower input rise and fall times.
QUICK REFERENCE DATA
GND=0 V; Tamb =25 °C.
Notes CPD is used to determine the dynamic power dissipation (PDin μW). =CPD× VCC2×fi× N+ Σ(CL× VCC2×fo) where:= input frequency in MHz;= output frequency in MHz;= output load capacitance in pF;
VCC= supply voltage in Volts;= total load switching outputs;
Σ(CL× VCC2×fo)= sum of the outputs. The condition is VI= GNDto VCC.

RECOMMENDED OPERATING CONDITIONS
LIMITING VALUES accordance with the Absolute Maximum Rating System (IEC 60134); voltages are referencedto GND (ground=0 V).
Notes The input and output voltage ratings may be exceeded if the input and output current ratings are observed. When VCC=0 V (Power-down mode), the output voltage can be 3.6 V in normal operation. For SO20 packages: above 70 °C derate linearly with 8 mW/K.
For TSSOP20 packages: above 60 °C derate linearly with 5.5 mW/K.
For DHVQFN20 packages: above 60 °C derate linearly with 4.5 mW/K.
