Successive Approximation
Registers
The MC14549B and MC14559B successive approximation
registers are 8–bit registers providing all the digital control and storage
necessary for successive approximation analog–to–digital conversion
systems. These parts differ in only one control input. The Master Reset
(MR) on the MC14549B is required in the cascaded mode when more
than 8 bits are desired. The Feed Forward (FF) of the MC14559B is
used for register shortening where End–of–Conversion (EOC) is
required after less than eight cycles.
Applications for the MC14549B and MC14559B include
analog–to–digital conversion, with serial and parallel outputs. Totally Synchronous Operation All Outputs Buffered Single Supply Operation Serial Output Retriggerable Compatible with a Variety of Digital and Analog Systems such as the
MC1408 8–Bit D/A Converter All Control Inputs Positive–Edge Triggered Supply Voltage Range = 3.0 Vdc to 18 Vdc Capable of Driving 2 Low–Power TTL Loads, 1 Low–Power Schottky
TTL Load or 2 HTL Loads Over the Rated Temperature Range Chip Complexity: 488 FETs or 122 Equivalent Gates
MAXIMUM RATINGS (Voltages Referenced to VSS) (Note 1.) Maximum Ratings are those values beyond which damage to the device
may occur. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/�C From 65�C To 125�C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high–impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS � (Vin or Vout) � VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either VSS or VDD).
