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 acceptsvoltageshigher than
VCC For AHC only:
operates with CMOS input levels For AHCT only:
operates with TTL input levels Specified from
−40to +85 and +125 °C.
DESCRIPTIONThe 74AHC/AHCT245 is a
high-speed Si-gate CMOS device.
The 74AHC/AHCT245 is an octal
transceiver featuring non-inverting
3-state bus compatible outputs in
both send and receive directions.
The74AHC245/74AHCT245features Output Enable (OE) inputfor easy
cascading and a send/receive (DIR)
input for direction control.
OE controls the outputs so that the
buses are effectively isolated.

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 packages: above 70 °C the value of PD derates linearly with 8 mW/K.
For TSSOP packages: above 60 °C the value of PD derates linearly with 5.5 mW/K.
