74ABT16827ADL,518

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT16827ADL,518 is a 20-bit non-inverting buffer and line driver manufactured by NXP USA Inc. It operates within a DC supply voltage range of 4.5 V to 5.5 V. The device features two independent 10-bit sections with NOR output enables (nOE1, nOE2). Propagation delays are typically 1.7 ns for high-to-low and 1.4 ns for low-to-high transitions at 5 V with a 50 pF load. Output drive capability reaches +64 mA in the low state and -32 mA in the high state. Quiescent supply current is 9 mA maximum when outputs are low.
