National Semiconductor DP83916 SONIC -16 handbook
SONIC-16 network interface controller is the second-generation Ethernet controller, specially designed to meet the demands of today's high-end 16-bit systems. Its system interface works with a high-speed DMA that typically consumes less than 8% of the bus bandwidth. Selectable bus modes provide both big-endian and little-endian byte ordering and a clean interface to standard microprocessors. SONIC-16's linked list buffer management system offers maximum flexibility in a variety of environments from PC-oriented adapters to high-speed motherboard designs. Furthermore, SONIC-16 integrates a fully compatible IEEE 802.3 Encoder-Decoder (ENDEC) allowing for a simple 2-chip solution for Ethernet when the SONIC-16 is paired with the DP8392 Coaxial Transceiver Interface. For increased performance, SONIC-16 implements a unique buffer management scheme to efficiently process receive and transmit packets in system memory. No intermediate packet copy is necessary. Receive buffer management uses three areas in memory for (1) allocating additional resources, (2) indicating status information, and (3) buffering packet data. During reception, SONIC-16 stores packets in the buffer area, then indicates receive status and control information in the descriptor area.

National Semiconductor 54F/74F322 handbook
54F322 Octal Serial Parallel Register with Sign Extend is an 8-bit shift register from National Semiconductor Corporation, which can be loaded either in serial or parallel and has TRI-STATE parallel outputs and a bi-state serial output. Parallel data inputs and parallel outputs are multiplexed to minimize pin count. State changes are initiated by the rising edge of the clock. Four synchronous modes of operation are possible: hold (store), shift right with serial entry, shift right with sign extend and parallel load, and an asynchronous Master Reset (MR) input overrides clocked operation and clears the register.
National Semiconductor LP3939 handbook
LP3939 is an integrated power amplifier driver designed specifically for Qualcomm's MSM3xxx and MSM5xxx series. It provides an interface to the baseband processor to control two independent power amplifiers in dual band applications. By integrating the necessary discrete components, the LP3939 significantly reduces board space and component cost.

National Semiconductor NM27P512 524 288-Bit (64K x 8) Processor Oriented CMOS EPROM handbook
The NM27P512 is a 512K Processor Oriented EPROM configured as 64k x 8. It's designed to simplify microprocessor interfacing while remaining compatible with standard EPROMs. It can reduce both wait states and glue logic when the specification improvements are taken advantage of in the system design. The NM27P512 is implemented in National's advanced CMOS EPROM process to provide excellent reliability and access times as fast as 120 ns. The interface improvements address two areas to eliminate the need for additional devices to adapt the EPROM to the microprocessor and to eliminate wait states at the termination of the access cycle. Even with these improvements, the NM27P512 remains compatible with industry standard JEDEC pinout EPROMs. The maximum specification for output turn-off time has been reduced, eliminating the need for wait states at the end of a read cycle. Also, the minimum specification for output hold time has been increased, eliminating the need for external circuitry to hold the data.
