74AC541B中文资料意法半导体数据手册PDF规格书

DESCRIPTION

The AC541 is an advanced CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power applications mantaining high speed operation similar to equivalent Bipolar Schottky TTL.

■ HIGH SPEED: tPD = 4 ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION: ICC =8 µA (MAX.) at TA = 25 °C

■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 VCC (MIN.)

■ 50Ω TRANSMISSIONLINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24 mA (MIN)

■ BALANCEDPROPAGATIONDELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGERANGE: VCC (OPR)= 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 541

■ IMPROVED LATCH-UP IMMUNITY
