Octal buffer/line driver; 3-state 74AHC541; 74AHCT541
FEATURES ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000V EIA/JESD22-A115-A exceeds 200V
CDM EIA/JESD22-C101 exceeds 1000V Balanced propagation delays All inputs have a Schmitt-trigger action Inputs accepts voltages higher than VCC For AHC only: operates with CMOS input levels For AHCT only: operates with TTL input levels Specified from −40to +85 °C and −40to +125 °C.
DESCRIPTIONThe 74AHC/AHCT541 is a high-speed Si-gate CMOS
device.
The 74AHC/AHCT541 are octal non-inverting buffer/line
drivers with 3-state bus compatible outputs.
The 3-state outputs are controlled by the output enable
inputs OE0 and OE1.
A HIGH on OEn causes the outputs to assume a
high-impedance OFF-state.
QUICK REFERENCE DATAGround=0 V; Tamb =25 °C; tr =tf≤ 3.0 ns.
Notes CPD is used to determine the dynamic power dissipation (PDin μW). =CPD× VCC2×fi+∑ (CL× VCC2×fo) where:= input frequency in MHz;= output frequency in MHz; (CL× VCC2×fo)= sum of outputs;= output load capacitance in pF;
VCC= supply voltage in Volts. The condition is VI= GNDto VCC.

RECOMMENDED OPERATING CONDITIONS
LIMITING VALUESIn accordance with the Absolute Maximum Rating System (IEC 134); voltages are referenced to GND (ground=0V).
Notes The input and output voltage ratings may be exceeded if the input and output current ratings are observed. For SO-package: above 70 °C the value of PD derates linearly with 8 mW/K.
For TSSOP-package: above 60 °C the value of PD derates linearly with 5.5 mW/K.
