1 / 13 page tm March 2007 ©1993 Fairchild Semiconductor Corporation www.fairchildsemi.com 74ABT373 Rev. 1.4 74ABT373 Octal Transparent Latch with 3-STATE Outputs Features ■ 3-STATE outputs for bus interfacing ■ Output sink capability of 64mA, source capability of 32mA ■ Guaranteed output skew ■ Guaranteed multiple output switching specifications ■ Output switching specified for both 50pF and 250pF loads ■ Guaranteed simultaneous switching, noise level and dynamic threshold performance ■ Guaranteed latchup protection ■ High-impedance, glitch-free bus loading during entire power up and power down ■ Nondestructive, hot-insertion capability General Description The ABT373 consists of eight latches with 3-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. Ordering Information Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number. Pb-Free package per JEDEC J-STD-020B.
