INTEGRATED CIRCUITS 74ALS563A/74ALS564A Latch flip/flop Product specification IC05 Data Handbook 1996 Jul 01 Philips Semiconductors Philips Semiconductors Product specification Latch/flip-flop 74ALS563A 74ALS564A FEATURES 74ALS373 74ALS563A/74ALS564A Octal transparent latch, inverting (3-State) Octal D flip-flop, inverting (3-State) 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. The data on the D inputs is transferred to the latch outputs when the enable (E) input is High. The latch remains transparent to the data input while E is High, and stores the inverted data that is present one setup time before the High-to-Low enable transition. The 74ALS564A is a complementary version of the 74ALS373 and has a broadside pinout configuration to facilitate PC board layout and allow easy interface with microprocessors. It is an 8-bit edge triggered register coupled to eight 3-State output buffers. The two sections of the device are controlled independently by clock (CP) and output enable (OE) control gates. The register is fully edge triggered. The state of the D input, one setup time before the Low-to-High clock transition is transferred to the cor...
