BC558B Bipolar transistor, PNP, 30V, 0.1A, 0.5W, TO-92

Description The SNx4LS24x, SNx4S24x octal buffers and line drivers are designed specifically to improve both the performance and density of three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and noninverting outputs, symmetrical, active-low outputcontrol (G) inputs, and complementary output control (G and G) inputs. These devices feature high fan-out, improved fan-in, and 400-mV noise margin. The SN74LS24x and SN74S24x devices can be used to drive terminated lines down to 133 O.

Features - Inputs Tolerant Down to 2 V, Compatible With 3.3-V or 2.5-V Logic Inputs - maximum tpd of 15 ns at 5 V - 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers - PNP Inputs Reduce DC Loading - hysteresis at Inputs Improves Noise Margins

Applications - servers - LED Displays - Network Switches - Telecom Infrastructure - Motor Drivers - I/O Expanders
