54ABT373 Octal Transparent Latch with TRI-STATE Outputs
General Description
The ’ABT373 consists of eight latches with TRI-STATE outputs for bus organized system applications. The flip-flops appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup times is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH the bus output is in the high impedance state. n Guaranteed multiple output switching specifications n Output switching specified for both 50 pF and 250 pF loads n Guaranteed simultaneous switching, noise level and dynamic threshold performance n Guaranteed latchup protection n High impedance glitch free bus loading during entire power up and power down n Nondestructive hot insertion capability n Standard Microcircuit Drawing (SMD) 5962-9321801
Features
n TRI-STATE outputs for bus interfacing n Output sink capability of 48 mA, source capability of 24 mA
