Working Principles

The 74FCT162H245CTPAG operates by receiving data from one bus and transmitting it to the other bus bidirectionally. The direction of data flow is controlled by the DIR pin. When DIR is set to a specific logic level, the device either transmits data from Bus A to Bus B or vice versa. The Transmit Enable pins (TE1-TE4) are used to enable/disable the data transmission on each channel.

The voltage level translation feature allows the IC to interface between different logic families, such as TTL and CMOS. This ensures compatibility and seamless communication between devices operating at different voltage levels.
