74HCT541D.652, Восемь буферных элементов/драйверов …The 74HCT541D is an octal non-inverting buffer/Line Driver with 3-state outputs. The device features two output enables (OE1 and OE2). A high on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC., Non-inverting outputs, TTL Input level, ±1µA Input leakage current, ±10µA Off-state output current, 160µA Supply current, Complies with JEDEC standard number 7A
