TC74VH245

The TC74VH245 is an advanced high speed CMOS OCTAL BUS TRANSCEIVER fabricated with silicon gate C2MOS technology.It achieves the hige speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. TC74VH245 is intended for two-way asynchronous communication between data busses.The direction of data transmission is determined by the level of the DIR input.

Features of the TC74VH245 are:(1)high speed:t_pd=4.0ns(typ.)at V_CC=5V;(2)low power dissipation:I_CC=4A(Max.)at T_a=25°C;(3)high noise immunity:V_NIH=V_NIL=28% V_CC(Min.);(4)balanced propagation delays:t_pLHt_pHL;(5)wide operating voltage range:V_CC(opr)=2V to 5.5V;(6)low noise:V_OLP=1.2V(Max.);(7)pin and function compatible with 74ALS245.

The absolute maximum ratings of the TC74VH245 can be summarized as:(1)supply voltage range,V_CC:-0.5V to 7.0V;(2)DC input voltage(DIR,G),V_IN:-0.5V to 7.0V;(3)DC BUS I/O voltage,V_I/O:-0.5V to (V_CC+0.5)V;(4)input diode current,I_IK:-20mA;(5)output diode current,L_OK:±20mA;(6)DC outout current,I_OUT:±25mA;(7)DC V_CC/GROUND current,I_CC:±75mA;(8)power dissipation,P_D:180mW;(9)storage temperature,T_stg:-65°C to 150°C.
