INTEGRATED CIRCUITS 74ALVCH16952 16-bit registered transceiver (3-State) Preliminary specification Supersedes data of 1994 Jul IC24 Data Handbook 1998 Sep 01 Philips Semiconductors Preliminary specification 16-bit registered transceiver (3-State) FEATURES 74ALVCH16952 DESCRIPTION • Complies with JEDEC standard no. 8-1A • CMOS low power consumption • MULTIBYTETM flow-through pin-out architecture • Low inductance, multiple center power and ground pins for The 74ALVCH16952 consists of two sections, each containing a dual octal non-inverting registered transceiver. Two 8-bit back to back registers store data flowing in both directions between two bi-directional busses. Data applied to the inputs is entered and stored on the rising edge of the clock (CPXX, where X is AB or BA) provided that the clock enable (CEXX) is LOW. The data is then present at the 3-State output buffers, but is only accessible when the output enable input (OEXX) is LOW. Data flow from A inputs to B outputs is the same as for B inputs to A outputs. minimum noise and ground bounce • Direct interface with TTL levels • Output drive capability 50Ω transmission lines @ 85°C QUICK REFERENCE DATA GND = 0V; Tamb = 25°C; tr = tf = 2.5ns PARAMETER SYMBOL CONDITIONS tPHL/tPLH Propagation delay CPnn, to An, Bn fMAX Maximum clock frequency CI Input capacitance CPD Power dissipation capacitance per buffer TYPICAL UNIT 3.2 ns 350 MHz 3.0 pF 30 pF VCC = 3.3V, CL = 50pF VCC = 2 2.5V, 5V CL = 30pF VI = GND to VCC1 NOTES: 1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V; (CL × VCC2 × fo) = sum of outputs.
