SY10E241 SY100E241 SY10E241 8-BIT SCANNABLE REGISTER Micrel, Inc. FEATURES SY100E241 DESCRIPTION ■ 1000ps max. CLK to output ■ Extended 100E VEE range of –4.2V to –5.5V The SY10/100E241 are 8-bit shiftable registers designed for use in new, high-performance ECL systems. Unlike the E141, the E241 features internal data feedback organized such that the SHIFT control overrides the HOLD, /LOAD control. Thus, the normal operations of HOLD and LOAD can be toggled with a single control line without the need for external gating. This configuration also enables switching to scan mode with the single SHIFT control line. The eight inputs D0–D7 accept parallel input data, while S-IN accepts serial input data when in shift mode. Data is accepted a set-up time before the rising edge of CLK. Shifting is also accomplished on the rising clock edge. A HIGH on the Master Reset pin (MR) asychronously resets all the registers to zero. ■ ■ ■ ■ SHIFT overrides HOLD, /LOAD control Asynchronous Master Reset Pin-compatible with E141 Fully compatible with industry standard 10KH, 100K ECL levels ■ Internal 75KΩ input pulldown resistors ■ Fully compatible with Motorola MC10E/100E241 ■ Available in 28-pin PLCC package PIN NAMES BLOCK DIAGRAM Pin S-IN D D0 Q Q0 R D D1 – D6 Q Q1 – Q6 R Function D0–D7 Parallel Data Inputs S-IN Serial Data Input SEL0 SHIFT Control SEL1 HOLD, /LOAD Control CLK Clock MR Master Reset Q0–Q7 Data Outputs VCCO VCC to Output BITS 1-6 D D7 Q Q7 R SEL1 (HOLD/LOAD) SEL0 (SHIFT) CLK MR M9999-032206 [email protected] or (408) 955-1690 Rev.: F 1 Amendment: /0 Issue Date: December 2005 SY10E241 SY100E241 Micrel, Inc.
