74AHC541; 74AHCT541
Octal buffer/line driver; 3-state
The 74AHC541; 74AHCT541 is an 8?-?bit buffer/line driver with 3?-?state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the associated outputs to assume a high?-?impedance OFF?-?state. Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.
Features and benefits
Wide supply voltage range from 2.0 to 5.5 V
Balanced propagation delays
High noise immunity
All inputs have a Schmitt-trigger action
Overvoltage tolerant inputs to 5.5 V
CMOS low power dissipation
Input levels:
For 74AHC541: CMOS level
For 74AHCT541: TTL level
Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
