74ACT533 Octal Transparent Latch with 3-STATE Outputs

April 2007

74ACT533 Octal Transparent Latch with 3-STATE Outputs
Features
ICC and IOZ reduced by 50% Eight latches in a single package 3-STATE outputs drive bus lines or buffer memory

tm

General Description
The ACT533 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 satisfying the input timing requirements 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.

address registers Outputs source/sink 24mA Inverted version of the ACT373 TTL-compatible inputs
