74ABTH16823A Datasheet | NXP Semiconductors

FEATURES - Two sets of high speed parallel registers with positive edge-triggered D-type flip-flops DESCRIPTION The 74ABT16823A 18-bit bus interface register is designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider data/address paths of buses carrying parity. The 74ABT16823A has two 9-bit wide buffered registers with Clock Enable (n CE) and Master Reset (n MR) which are ideal for parity bus interfacing in high microprogrammed systems. The registers are fully edge-triggered. The state of each D input, one set-up time before the Low-to-High clock transition is transferred to the corresponding flip-flop’s Q output. Two options are available, 74ABT16823A which does not have the bus-hold feature and 74ABTH16823A which incorporates the bus-hold feature . - Ideal where high speed, light loading, or increased fan-in are required with MOS microprocessors - Live insertion/extraction permitted - Power-up 3-State - 74ABTH16823A incorporates bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs - Power-up Reset - Output capability: +64m A/- 32m A - Latch-up protection exceeds 500m A per Jedec Std 17 - ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model QUICK REFERENCE DATA SYMBOL t PLH t PHL CIN COUT ICCZ ICCL PARAMETER Propagation delay n CP to n Qx Input capacitance Output capacitance Quiescent su supply ly current CONDITIONS Tamb = 25°C; GND = 0V CL = 50p F; VCC = 5V VI = 0V or VCC VO = 0V or VCC; 3-State Outputs disabled; VCC = 5.5V Outputs low; VCC = 5.5V TYPICAL 2.3 1.9 4 6 500 9 UNIT ns p F p F µA m A ORDERING INFORMATION PACKAGES 56-Pin Plastic SSOP Type III 56-Pin Plastic TSSOP Type II 56-Pin Plastic SSOP Type III 56-Pin Plastic TSSOP Type II TEMPERATURE RANGE - 40°C to +85°C - 40°C to +85°C - 40°C to +85°C - 40°C to +85°C OUTSIDE NORTH AMERICA 74ABT16823A DL 74ABT16823A DGG 74ABTH16823A DL 74ABTH16823A DGG NORTH AMERICA BT16823A DL...
