TC7WH245FU/FK
TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
TC7WH245FU,TC7WH245FK
Dual Bus Transceiver
FEATURES
• High Speed
: t_pd = 4.0 ns (typ.)
at V_CC = 5 V, C_L = 15pF
• Low Power Dissipation
: I_CC = 2 μA (Max) at Ta = 25°C
• High Noise Immunity
: V_NIH = V_NIL = 28% V_CC (Min.)
• Balanced Propagation Delays: t_pLH ≈ t_pHL
• Wide Operating Voltage Range: V_{CC (opr)} = 2 to 5.5 V
• Low Noise
: V_OLP = 0.8 V (Max.)
APPLICATION NOTES
1) Do not apply a signal to any bus terminal when it is in the
output mode. Damage my result.
2) All floating (high impedance) bus terminals must have their
input levels fixed by means of pull up or pull down resistors or
bus terminator IC’s such as the TOHSIBA TC40117BP.
3) A parasitic diode is formed between the bus and Vcc terminals.
Therefore bus terminal can not be used to interface 5V to 3V
systems directly
