TC74AC377

The TC74AC377 is an advanced high speed CMOS octal D-type flip-flop fabricated with silicon gate and doublelayer metal wiring C2MOS technology.It achieves the high speed operation similar to equivalent Bipolar Schottky TTL, while maintaining the CMOS low power dissipation.These 8-bit D-type flip-flops are controlled by a clock input(CK) and a output enable input (G).

Features of the TC74AC377 are:(1)high speed:fMAX=140MHz (typ.) at Vcc= 5V; (2)low power dissipation:Icc= 8A (max.) at Ta=25; (3)high noise immunity:VNIH=VNIL=28% Vcc(min.); (4)pin and function compatible with 74F377; (5)available in DIP, SOIC and SOP packages; (6)balanced propagation delays:tpLH= tpHL; (7)wide operating voltage range:Vcc(opr.) = 2V~5.5V.The signal level applied to the D inputs are transferred to Q outputs during the positive going transition of CK.When the G is high, the eight outputs are in a high impedance state.All inputs are equipped with protection circuits against static discharge or transient excess voltage.

The absolute maximum ratings of the TC74AC377 can be summarized as:(1)supply voltage range:-0.5 to 7.0V;(2)DC input voltage:-0.5 to Vcc+0.5V;(3)DC output voltage:-0.5 to Vcc+0.5V;(4)input diode current:±20mA;(5)output diode current:±50mA;(6)DC output current:±50mA;(7)DC Vcc/ground current:±200mA;(8)power dissipation:500mW; (9)storage temperature:-65 to 150;(10)lead temperature:300.The information contained herein is presented only as guide for the applications of our products.
