74HC541; 74HCT541
Octal buffer/line driver; 3-state
The 74HC541; 74HCT541 is an octal non-inverting buffer/line driver with 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Features and benefits
Wide supply voltage range from 2.0 to 6.0 V
CMOS low power dissipation
High noise immunity
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
Non-Inverting outputs
Complies with JEDEC standards:
JESD8C (2.7 V to 3.6 V)
JESD7A (2.0 V to 6.0 V)
Input levels:
For 74HC541: CMOS levels
For 74HCT541: TTL levels
- ESD protection:
HBM JESD22-A114F exceeds 2 kV
MM JESD22-A115-A exceeds 200 V
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
