Overview
The 74LV245DB,118 is an 8-bit transceiver with 3-state outputs, manufactured by NXP USA Inc. This device is part of the 74LV series, which is known for its low-voltage Si-gate CMOS technology. It is pin and function compatible with the 74HC/HCT245 series. The 74LV245DB,118 features an output enable (OE) and a send/receive (DIR) pin for direction control, allowing for flexible data transmission and reception. A HIGH on the OE pin causes the outputs to assume a high-impedance OFF-state, which is useful for bus applications.
