74LVC841A 10-bit transparent latch with 5 V tolerant inputs/outputs 3-state Rev. 4 2 April 2013 Product data sheet 1. General description The 74LVC841A is a 10-bit transparent latch featuring separate D-type inputs for each latch and 3-state outputs for bus applications. A latch enable (pin LE) input and an output enable (pin OE) input are common to all internal latches. The device consists of ten transparent latches with 3-state true outputs. When pin LE is HIGH, data at the Dn inputs enters the latches. In this condition, the latches are transparent, that is, a latch output changes each time its corresponding D-input changes. When pin LE is LOW, the latches store the information that was present at the D-inputs a set-up time preceding the HIGH to LOW transition of pin LE. When pin OE is LOW, the contents of the ten latches are available at the outputs. When pin OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the pin OE input does not affect the state of the latches. Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices as translators in mixed 3.3 V and 5 V applications. 2.
