PDF datasheet for the Texas Instruments SN74LVTH245APW, a 3.3 V octal bus transceiver with three-state outputs and bus-hold inputs. PW indicates the TSSOP package, and the E05 ending is part of TI's orderable part code. The 24.7 KB file is a compact product sheet. Use it to find the direction and output-enable pins when tracing level-sensitive buses on network, industrial or computer boards. Because bus hold keeps unused inputs at their last state, account for it when you measure floating lines with a meter.
