TC74VHC541FT

The TC74VHC541FT is designed as one kind of advanced high speed CMOS octal bus buffer that is fabricated with silicon gate CMOS technology. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.

Features of the TC74VHC541FT are:(1)High speed: tpd = 3.7 ns (typ.) at VCC = 5 V; (2)Low power dissipation: ICC = 4 A (max) at Ta = 25C; (3)High noise immunity: VNIH = VNIL = 28% VCC (min); (4)Power down protection is provided on all inputs.; (5)Balanced propagation delays: tpLH to tpHL; (6)Wide operating voltage range: VCC (opr) = 2 V to 5.5 V; (7)Low noise: VOLP = 1.2 V (max); (8)Pin and function compatible with 74ALS540/541.

The absolute maximum ratings of the TC74VHC541FT can be summarized as:(1)Supply voltage range: -0.5 to 7.0 V;(2)DC input voltage: -0.5 to 7.0 V;(3)DC output voltage: -0.5 to VCC + 0.5 V;(4)Input diode current: -20 mA;(5)Output diode current: ±20 mA;(6)DC output current: ±25 mA;(7)DC VCC/ground current: ±75 mA;(8)Power dissipation: 180 mW;(9)Storage temperature: -65 to 150 °C.
