description

GND

The SN74BCT533 is an 8-bit transparent D-type

latch with 3-state outputs designed specifically for

driving highly capacitive or relatively low-imped-

ance loads. It is particularly suitable for

implementing buffer registers, I/O ports, bidirec-

tional bus drivers, and working registers.

When the latch-enable (LE) input is high, the Q outputs follow the complements of the data (D) inputs. When

LE is taken low, the Q outputs are latched at the inverse of the levels set up at the D inputs. The SN74BCT533

provides inverted data at its outputs.

A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high

or low logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive

the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus

lines without need for interface or pullup components.

The output-enable (OE) input does not affect the internal operations of the latch. Previously stored data can be

retained or new data can be entered while the outputs are in the high-impedance state.

The SN74BCT533 is characterized for operation from 0°C to 70°C.
