BM
CAPABILITY
(Plastic Package)
(Micro Package)
s SYMMETRICAL OUTPUT IMPEDANCE:
|IOH| = IOL = 24 mA (MIN)
s BALANCED PROPAGATION DELAYS:
ORDER CODES :
74AC244B
74AC244M
tPLH ≅ tPHL
s OPERATING VOLTAGE RANGE:
VCC (OPR) = 2V to 6V
s PIN AND FUNCTION COMPATIBLE WITH
74 SERIES 244
s IMPROVED LATCH-UP IMMUNITY
mantaining high speed operation similar to
equivalent Bipolar Schottky TTL.
G control output governs four BUS BUFFERs.
This device is desibned to be used with 3 state
memory address drivers, etc.
