QS74FCT825ATQX Datasheet
READ MODE The DS1250W executes a read cycle whenever WE (Write Enable) is inactive (high) and CE (Chip Enable) and OE (Output Enable) are active (low). The unique address specified by the 19 address inputs (Ao - Ai8) defines which of the 524,288 bytes of data is to be accessed. Valid data will be available to the eight data output drivers within tACC (Access Time) after the last address input signal is stable, providing that CE and OE (Output Enable) access times are also satisfied. If OE and CE access times are not satisfied, then data access must be measured from the later-occurring signal (CE or OE) and the limiting parameter is either tco for CE or tOE for OE rather than address access.

The TX5001 hybrid transmitter is ideal for short-range wireless data applications where robust operation, small size, low power consumption and low cost are required All critical RF functions are contained in the hybrid, simplifying and speeding design- in. The TX5001 includes provisions for both on-off keyed (OOK) and amplitude-shift keyed (ASK) modulation. The TX5001 employs SAW filtering to suppress output har- monics, facilitating compliance with FCC Part 15 and similar regulations.
