74ABTH16841A Datasheet | NXP Semiconductors

FEATURES - High speed parallel latches - Live insertion/extraction permitted - Extra data width for wide address/data paths or buses carrying - Power-up 3-State - 74ABTH16841A incorporates bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs parity DESCRIPTION The 74ABT16841A Bus interface latch is designed to provide extra data width for wider data/address paths of buses carrying parity. The 74ABT16841A consists of two sets of ten D-type latches with 3-State outputs. The flip-flops appear transparent to the data when Latch Enable (n LE) is High. This allows asynchronous operation, as the output transition follows the data in transition. On the n LE High-to-Low transition, the data that meets the setup and hold time is latched. Data appears on the bus when the Output Enable (n OE) is Low. When n OE is High the output is in the High-impedance state. Two options are available, 74ABT16841A which does not have the bus-hold feature and 74ABTH16841A which incorporates the bus-hold feature . - Power-up reset - Ideal where high speed, light loading, or increased fan-in are - Output capability: +64m A/- 32m A - Latch-up protection exceeds 500m A per Jedec Std 17 - ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model required with MOS microprocessors QUICK REFERENCE DATA SYMBOL t PLH t PHL CIN COUT ICCZ ICCL PARAMETER Propagation delay n Dx to n Qx Input capacitance Output capacitance Quiescent supply 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 3.1 2.2 4 7 500 10 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 74ABT16841A DL 74ABT16841A DGG 74ABTH16841A DL 74ABTH16841A DGG NORTH...
