DESCRIPTION
The 74ALS563A is an octal transparent latch coupled to eight 3-State output devices. The two sections of the device are controlled independently by enable (E) and output enable (OE) control gates.
The 74ALS563A is a complementary version of the 74ALS373 and has a broadside pinout configuration to facilitate PC board layout and allow easy interface with microprocessors.

FEATURES

• 74ALS564A is broadside pinout and inverting version of 74ALS374
• Inputs and outputs on opposite side of package allow easy interface to microprocessors
• Useful as an input or output port for microprocessors
• 3-State outputs for bus interfacing
• Common output enable
• 74ALS573A and 74ALS574A are non-inverting version of 74ALS563B and 74ALS564A respectively
