Product Summary

The TC74VHC245F is an advanced high speed CMOS OCTAL BUS TRANSCEIVER fabricated with silicon gate C2MOS technology. The TC74VHC245F achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The TC74VHC245F is intended for two-way asynchronous communication between data busses. The direction of data transmission is determined by the level of the DIR input. The enable input (G ) can be used to disable the device so that the busses are effectively isolated.

Parametrics

TC74VHC245F absolute maximum ratings: (1)Supply voltage range VCC: -0.5 to 7.0 V; (2)DC input voltage (DIR, G)VIN: -0.5 to 7.0 V; (3)DC bus I/O voltage VI/O: -0.5 to VCC + 0.5 V; (4)Input diode current IIK: -20 mA; (5)Output diode current IOK: ±20 mA; (6)DC output current IOUT: ±25 mA; (7)DC VCC/ground current ICC: ±75 mA; (8)Power dissipation PD 180 mW; (9)Storage temperature Tstg: -65 to 150 °C.

Features

TC74VHC245F features: (1)High speed: tpd = 4.0 ns (typ.)at VCC = 5 V; (2)Low power dissipation: ICC = 4 μA (max)at Ta = 25°C; (3)High noise immunity: VNIH = VNIL = 28% VCC (min); (4)Balanced propagation delays: tpLH −∼ tpHL; (5)Wide operating voltage range: VCC (opr)= 2 V to 5.5 V; (6)Low noise: VOLP = 1.2 V (max); (7)Pin and function compatible with 74ALS245.
